Hoymiles HM Inverter

Hello

I installed openhab and it runs very well. I would like to display the data from my solar system in Openhab. There is a script for Homeassistant which I tried to build into my system, but it doesn’t really work. Maybe one of you has advice.

Sorry for the english, it was translated with google :smile:

Hi,

It is probably too late, but have a look at that: GitHub - tbnobody/OpenDTU: Software for ESP32 to talk to Hoymiles Inverters
It works like a charm ! You just need to build the hardware device (easy to do), flash the firmware and
configure MQTT.

there is also a similar project:

@gd35 do you know the differences in this projects? Both have the chip for WLAN and the other chip to receive the hoymiles data.
Bot can forward to MQTT

@timguy I do not know what are differences between these two projects. Both of them came from discussions from the same forum: Wechselrichter Hoymiles HM-xxxx 2,4 GhZ Nordic Protokoll? - Mikrocontroller.net
I saw that (in GitHub - tbnobody/OpenDTU: Software for ESP32 to talk to Hoymiles Inverters) the Ahoy tool is presented as a related project.
