HMS-400 1T Homeassistant

Third party integrations
1

Hello, my dad recently bought and installed a new solar system from kleines Kraftwerk. The inverter and the DTU are from hoymiles. For him, I set up the app, and it works perfectly fine. I want to integrate the solar panels into HA but when I tried to integrate it with the Hoymiles addon suaveolent/ha-hoymiles-wifi, I didn’t get the entities like the Watts that were produced, I only got DTU restart, inverter power limit, inverter Turn off and invter Turn on. I read that it’s not compatible, but I just wanted to try it out. Furthermore, I’ve seen there’s another addon, but that didn’t work for me because I have no access to the global.hoymiles.com website. It tells me when I try to log in that I only have access to the hoymiles home app.

My question now is how to integrate my HMS 400 1T into HA?

I don’t know anything about the integrations that try to make the Hoymiles DTU work. But the HMS-400-1T is on the list of inverters supported by OpenDTU, Inverter Overview - OpenDTU Documentation

OpenDTU provides the data via MQTT. I have my HMS-800-2T integrated that way.

Yes, and blinkyparts does a kit for integrating it.

Make sure you get the matching radio kit.
