For reading the power meter of my house(mbus I suppose), I use Youless LS120 with the “Youless and Enerlogic” app on HP2023. With the modbus adaptor I am going to read my Growatt inverter with the app [SolarEdge + Growatt TCP modbus App voor Homey | Homey](https://homey.app/nl-nl/app/solaredge.modbus/SolarEdge-+-Growatt-TCP-modbus/) The [https://www.amazon.nl/dp/B07DNWM62H/ref=pe\_28126711\_487102941\_TE\_SCE\_dp\_1](https://www.amazon.nl/dp/B07DNWM62H/ref=pe_28126711_487102941_TE_SCE_dp_1) does support HTTP client, so it might be controlled by Homey by HTTP GET and PUT. Otherwise you have to make an app for your own devices. ---
