Introduction
The P1 meter is a device that can be connected to the smart meter in the fuse box. This gives you more insight into your energy consumption. It is a building block of a smart and economical electrical installation, because it can send relevant energy consumption data to home energy management systems like the Ecosoft Smart Grid Controller.
Connect the P1 meter with the supplied cable to the P1 port of the smart meter. This allows the P1 meter to read current energy consumption and meter readings. The P1 meter can pass this data on to Ecosoft devices and other devices. This makes it possible to better regulate energy consumption (and the return of energy to the grid). This device is suitable for 1-phase and 3-phase systems without additional costs.
The P1 meter is able to perform a useful task for supported inverters of PV systems, namely to directly control a PV system to save costs on the feed-back of electricity to the grid.
For supported inverters, the P1-meter can (via the Modbus protocol) regulate back or set to zero the inverter’s output power if the price falls below a certain value.
Installing the P1-meter
WiFi only P1-meter for newer smart meters
When using a newer smart meter (ESMR 5.0), power supply via the P1-port is possible. An adapter is not needed in this case. (Note: if you have more than one P1-meter, then connect both to an active splitter to guarantee sufficient power supply for each P1-meter.)
WiFi only P1-meter for older smart meters
This diagram applies to a P1-meter with WiFi only (or if you don’t use a cable network connection).
The P1-meter requires power supply via an adapter in this case because an older smart meter is used.
P1-meter with WiFi and LAN without PoE
If the P1-meter has a LAN connector, (optionally) connect a network cable (ethernet) to it. Connect a USB power supply adapter to this type of P1-meter, because PoE is not available here.
P1-meter with WiFi and LAN supporting PoE
If a network cable is used and PoE (power over ethernet) is available on the network cable you have connected, the P1-meter doesn’t need a USB power supply adapter. If your network doesn’t supply PoE, then use a power adapter.
Connecting the P1-meter – general description
Only when a connection via the wireless network (WiFi) is made, the Ecosoft P1-meter can be powered via the P1-port of newer smart meters (ESMR 5.0), and is an external power supply adapter not necessary. For old smart meters, or when using a wired network (ethernet), use the power supply adapter and connect it to the USB port, or use Power over Ethernet via the wired network. Power over Ethernet requires the PoE variant of the Ecosoft P1-meter.
Connect the supplied data cable to the P1-port of the smart meter and connect the other end to the P1-port of the Ecosoft P1-meter. When the P1-meter receives valid data, the LED of the P1-port will switch on after a few seconds.
The Ecosoft P1-meter can work with wireless WiFi, but a wired network is preferable. Connect an ethernet cable to the LAN connector to establish a wired connection to your network.
On the opposite side of the P1-port of the P1-meter, there is an USB-port for power supply. There is an ethernet port (LAN) next to it, for P1-meter variants supporting ethernet. This is shown on the stickers on the device: USB and LAN.
Network Configuration
Ethernet Configuration
P1-meters with LAN can be connected to the network with a network cable or via wireless WiFi. We recommend using a wired connection.
- Connect the P1-meter with an ethernet cable to your network.
When connected to the network, the device will automatically try to get an IP address via DHCP. Also, it will register itself via mDNS under the name ecop1.local.
- On a PC or smartphone in your network, open a browser and visit http://ecop1.local
- If you are asked to login, use these credentials:
Username = eco
Password = power
If you want to make sure the connection is never made via WiFi, there are two ways to accomplish that:
- Don’t configure WiFi (which would involve filling in the WiFi password in the WiFi Settings). The result is that using a .local address (mDNS) will only access the P1-meter via ethernet.
- Or don’t use a .local address (mDNS) but only the explicit IP address of the P1-meter. Find this IP address (eth) in System -> Information
WiFi Configuration
Perform the WiFi configuration if you have a P1-meter WiFi only, if you want to use WiFi instead of LAN.
(Possibly you will need to turn off mobile data during the configuration procedure.)
At the start of the procedure, the P1-meter is available as WiFi access point.
- On your phone, go to the WiFi settings and connect to the network called “EcoP1”.
- If this network name is not listed, slide the button on the device left and right two times to make the P1-meter a WiFi Access Point again.
- In the browser on your phone, go to http://192.168.4.1. This is a temporary address; after configuration the P1-meter will no longer be reachable at this address.
- When prompted to log on, use the same credentials as for the wired connection.
Username = eco
Password = power
Once you have access to the device, adjust the network settings as follows:
- In the menu, choose Configuration -> Configure WiFi if you are not on the WiFi page already.
- The device will show a list of detected WiFi networks. Select your WiFi network and fill in its password.
- The hostname (mDNS) is adjustable here as well. On default, this is “EcoP1”. You can use this name later to access the P1-meter via browser or Ecosoft App. When the name remains “EcoP1”, the P1-meter will be accessible via http://ecop1.local.
- Press save. It may take up to a minute before the connection to your WiFi network has been established. When this succeeds, the browser will show the new IP address that your network has assigned to the P1-meter, and will visit this address within a few seconds. After that, the main screen of the P1-meter will be visible.
- After completion, the P1-meter will be accessible within your own WiFi network and no longer operate as a WiFi access point.
- Your mobile phone needs to be reconnected to your own WiFi network; this usually happens automatically. When requested to log in, fill in eco and power.
- If the main screen does not appear or you are not requested to log in, you can try to reload the page or access the P1-meter via http://ecop1.local or the new IP address.
Advanced Network Settings
- In the menu System -> Consoles -> Console you may adjust advanced network settings. There are a number of commands available.
Do you have a P1-meter WiFi only? Then do not turn off WiFi. Have you configured a WiFi connection? Then don’t turn off WiFi either. If you haven’t configured WiFi, but are you using an Ethernet connection via the network cable instead? Only in that case it might be desirable to turn off WiFi completely, so that the P1-meter is no longer a WiFi access point.
Turn off WiFi completely:
WiFi 0
When WiFi is turned off this way, the P1-meter can only be reached via ethernet. The P1-meter cannot become a WiFi access point either, which is necessary to configure WiFi, when this is desired.
To turn on WiFi functionality again, use the command:
WiFi 1
If DHCP doesn’t work or is not desired to establish the IP in the wired network (0.0.0.0 means use DHCP (default setting)):
EthIPAddress xxx.xxx.xxx.xxx
The commands EthSubnetmask, EthGateway, EthDNSServer1, EthDNSServer2 will work the same way.
Restart the devices (System > Restart) to apply the new network options.
Details of the network connection are retrieved as follows:
- Menu System -> Information
The network properties (including IP addresses) are shown.
Using the P1-meter
Accessing the web interface
The Ecosoft P1-meter is accessible via the assigned IP address or – if your phone supports mDNS – via the hostname of the P1-meter (e.g. http://ecop1.local). The IP address may change if your WiFi network assigns another IP address to the P1-meter, for example when the P1-meter has been disconnected from the outlet for some time, and reboots. The hostname, however, will remain the same and might be more convenient to use.
When opening the web interface, you will be prompted to log on. The default credentials are:
Username: eco
Password: power

Security Warning about Modbus TCP
Modbus TCP communication is not secured. Other devices in the same network may be able to send messages via Modbus TCP, and by doing so control or read out devices. When Modbus TCP is used anyway, make sure there are no untrusted devices present on the same network (including IoT devices connected to the WiFi network), or implement data separation by connecting devices that need to communicate via Modbus TCP to a separate network.
When using Modbus RTU these disadvantages do not apply. Only devices connected to the Modbus data cable can send messages to each other.
The P1-meter can read data from a solar energy inverter supporting the SunSpec Modbus TCP protocol. This communication can take place entirely within your own network. If necessary, ask your technician to activate Modbus TCP on your inverter, and ask which IP address and port are available. The default port is 502; SolarEdge usually uses port 1502.
Protocol: SunSpec Modbus or Growatt.
IP address: IP address of the inverter
Port: TCP port of the inverter used for the communication
Unit ID: Unit ID used for communication, for example 126 for SMA devices.
Read interval: Time elapse (in seconds) between two data readouts.
Testing
To determine if the inverter is read correctly, click on the blue Test button. This way you can view the power consumption value that has been read and determine if any error occurred.
Prevent feed back if electricity is cheaper than: When electricity is cheaper than the value that is chosen, the power output of the inverter will be reduced in such a way that no more energy will be produced than is consumed (the sum of all phases), so that as a result, no energy is fed back to the grid. This is an approximation, because there are delays and inaccuracies when controlling the inverter.
Turn off if electricity is cheaper than: When electricity is cheaper than the specified value, the power output of the inverter is reduced to zero.
The price that is used for calculations is the market prices without taxes and without other surcharges.

Connection to the Ecosoft server
Connecting the P1-meter
Optionally, data can be stored on the Ecosoft server in the cloud. This way data can be stored for a long period of time, and will be accessible by you from outside your own network.
Additionally, remote action can be performed. The connection to the Ecosoft server is optional, and not necessary for the proper functionality of the P1-meter.
Access and use of the server is possible with a valid license key which is stored on the device (Ecosoft P1-meter) itself. The license key can be extended when needed.
The Ecosoft server has the following web address:
https://cloud.ecosoftenergie.nl
It is necessary to create an account at the server mentioned above to put it in use. Thereafter you can connect one or more devices to this account.
To connect a P1-meter to your account:
• Open the web interface of the device itself (the P1-meter)
• Click on Configuration
• Click on Configure Cloud
• Click on the button “Pair device”
The browser will open a new window or tab, and there you will be redirected to cloud.ecosoftenergie.nl. It might be you’ll have to log in there again.
• Click on the Confirm button for confirmation
• Click on Register to add the device to your account
• Copy the activation code
• Return to the window or tab of the P1-meter, and paste the activation code in the edit box, and click on Save.
Note: the activation code is for single use only and does not have to be stored.
When the connection is made, you can choose which data should be sent to the server:
• Events: For example, switching to another energy consumption state.
• Perform actions: Enable this option to allow remote control of the P1-meter via the server.
The data is sent periodically (not real-time). Especially when the connection has just been initiated, it may take a while before all data has been sent. Expect actions will be performed with a delay, after 5 minutes at most.
Stop sending data
You can stop sending data at any time via the web interface of the P1-meter. You can do this by disabling the options (untick the boxes) or by disconnecting the P1-meter from the Ecosoft server. Sending data will then be stopped. Disconnecting does not remove data from the server, but will stop sending data.
Remove data from server
Note: Removal of data from the server is possible at the server itself, via the “Delete Device” button on the P1-meter page at the server.
Accessing data and graphs
The data is presented in graphs. Open https://cloud.ecosoftenergie.nl in your browser and sign on, or access it via the web interface of the P1-meter: click on Cloud Connections and click on the link “Device at Ecosoft server”.
In the Ecosoft Dashboard, click on the icon of the P1-meter and then on the Power Consumption tab.
When the P1-meter is connected to the smart meter, data on energy consumption and feeding electricity back can be read out. The data can be shown in the cloud in graphs, together with dynamic electricity tariffs. If you have a Time Of Use contract with your electricity provider, you can obtain insight on how much relatively cheap or expensive electricity you are using.
Ecosoft Server Menu
The Ecosoft cloud server has a number of menu items in the pane on the left: Dashboard, Devices, Profile, Shop, and Sign out.
Ecosoft Server Dashboard

Connection to Ecosoft devices
The P1 data that is read out by the P1-meter can be used by other Ecosoft products, to determine when to perform actions such as switching on a power consuming device. For example, and Ecosoft SGC can put a heat pump in a higher energy consumption state, to benefit from energy instead of feeding it back to the grid.
See the manual of the Ecosoft device on how to establish the connection.
Solving Problems
The P1-meter is not accessible in the network (ethernet)
Check the network cable and the network connection. If DHCP is active, but mDNS doesn’t work, you can try to find the IP address of the P1-meter by looking it up in your router.
As an alternative, you can access the P1-meter via WiFi (only when WiFi is turned on).
The P1-meter is not accessible in the network (WiFi)
You can access the P1-meter via WiFi (only when WiFi is turned on). Check if the P1-meter is available as a WiFi access point. To do this, search for network ecop1 on your smartphone. Check if WiFi still works and the signal is strong enough at the location of the P1-meter.
(It may have another name if you changed the network name of the P1-meter yourself.) If this WiFi Access Point is present, reconnect the P1-meter to your WiFi network as described at Network Configuration.
Check if WiFi is still working and its signal is strong enough at the site where the P1-meter is located. To reset the WiFi settings of the P1-meter, move the slider at the bottom of the P1-meter left and right 2 times (that is moving it 4 times in total). After that, the P1-meter should become available as a WiFi access point. Then connect it to your own WiFi network.
The P1-meter is visible in the network, but accessing the P1-meter fails.
To reset the password, you can perform a factory reset. Move the slider at the bottom of the P1-meter left and right 5 times (that is moving it 10 times in total. With this, the network settings will be reset as well.

Ecosoft Energy App – Free Energy Planner
The Free Energy Planner is also available at https://www.ecosoftenergy.com/energieplanner/
With this Free Energy Planner, you can manually determine when the energy price is lowest. The result is valid for today. (An Ecosoft device like SG-Hub or EcoSwitch can automatically calculate this daily, and switch on and off your electrical device automatically.)
The settings of the Free Energy Planner are:
● For how long do you need to use power?
● When must power usage be finished?
● With what time steps can you delay starting your device?
The time-step option is used this way: If an electrical device supports a delayed start, let’s say a delay of 0:15 and multiples of 0:15, set the time-step to 0:15. Is a delay of multiples of 1 hour supported? Set the time-step to 1 hour.
After you completed the setup, the result will show.
The dark green or even red bar shows the costs when you don’t plan at all, but start to consume energy right away. The light green bar shows the costs when you follow the advice of the Free Energy Planner. It will also show the percentage of the price you save.
With this tool you can reduce costs and CO2 emission right away.
