Purpose
The difference of this app and the already existing solar panels app is that this app reads the data directly from the inverter.
The solaredge api and others are mostly limited to 300 calls/ day, so you get only updates every 10-15 minutes.
The modbus app receives data every few seconds.
If you have the Solaredge energy monitor installed you can maximize your self-consumption and limit your exported power by using it. You can make flows based on your generated solar power, exported power, imported power or current power consumption.
The iOS / android app from Growatt or Solaredge are fine, so it is not the purpose to create this app again.
Growatt
Homey app to receive near realtime data from your Growatt - SPA, SPH or TL-X XXX Hybrid Inverter and others in the same range using local Modbus TCP
To enable modbus tcp on your Growatt converter do the following described in this doc Dropbox - Setup Growatt.pdf - Simplify your life
General information can be found at: Growatt Protocol
Special thanks for Luc Van Laer for his guidance and help to add support for Growatt inverters
Supported devices
Following devices are supported
Growatt - SPA, SPH, TL-X XXX Hybrid Inverter and others in the same range
Wattsonic 3rd generation
Wattsonic gen3 inverter and their clones (sunways, solinteg, A-Tronix, St-ems).
For more information see Wattsonic Hybrid Inverter Gen3 Modbus RTU Protocol | SmartHome.Exposed
Sungrow inverters with meters and a battery
Huawei inverters with meters and a battery (read only mode)
Solaredge
Homey app to receive near realtime data from your Solaredge solar installation using local Modbus TCP
Links
The app is now live in the Homey app store: Homey App Store
Github code: Github Link
Supported devices
Following devices are supported
- Inverters with SetApp and with display
- Modbus energy Meter
- Storedge devices (DC connected battery storage)
Enable Modbus TCP on your inverter
Modbus TCP is disabled by default on all inverters, you have to enable this function
Important: The TCP server idle time is 2 minutes after starting. In order to leave the connection open, the request should be made within 2 minutes. The connection can remain open without any MODBUS requests.
General information can be found at: Sunspec Protocol
Inverters with SetApp
- Enable wifi direct on the inverter.
- Connect to the inverter access point like you would for a normal wifi network. The wifi password is published at the right side of the inverter.
- Then open up a browser and go to http://172.16.0.1 .
- From this webpage you can enable modbus TCP without setApp or installer account.
Inverters with display (without SetApp)
Your CPU firmware has to be at least v 3.xxxx, if this is not the case, upgrade your firmware.
Firmware upgrade
Go to the menu by the following steps:
- Switch of the DC power
- Long press the ‘OK’ button for a few seconds
- Release the ‘OK’ button
- The screen will ask a password, this is ‘12312312’ (the 2nd button from the left is ‘1’, the 3rd button is ‘2’, etc…)
- Go to Communication → LAN Conf → Modbus TCP (the default port is 502).
- To modify the TCP port, select Modbus TCP → TCP Port, set the port number and long-press Enter
Advanced configuration:
Better read the Solaredge documentation before use:
https://www.photovoltaikforum.com/core/attachment/88445-power-control-open-protocol-for-solaredge-inverters-pdf/
To use Homey as a Remote Control, the "Storage Mode"has to be changed to “Remote Control”(in a flow action), afterwards you can configure the Remote Control and Charge and Discharge parameters with a flow action.

Thanks
Thanks to Richard Barkestam and Jelger Haanstra for the SMA Energy app, where this app is based on.
Nice to know:
This Solaredge app is currently one of the first to support advanced Storedge functions.
Not even the official SolarEdge app or website support these advanced configurations. (nor other domotica stuff)
