Is it possible to use ESPAltherma with ROTEX HPSU Compact 508 manufactured in 2014? Thanks in advance.

Hi @vojtechalbl, welcome! I believe ALTHERMA(HPSU6_ULTRA).h should be a good file definition for your heat pump. Test and let us know if you get what you need!

So, I am using M5StickC and ALTHERMA(HPSU6_ULTRA).h. My board has 8pin X10A port. I have used pins according to your instructions.

Unfortunately, I am not receiving any data:-(.

Any suggestions?

Here is my mqtt output in homeassistant:

Hi @vojtechalbl, Seems that your m5 has no input power and runs on battery. Make sure that the ground is properly connected to the ground of the X10A port and that if needed the M5stickc is powered with external USB charger.

Thank you very much for your advise.

You were right. I forgot to connect M5stickc to the GND. It is powered with external USB charger.

Now the output is full of data.
