This thread is talk about the eBUS adapter and ebusd software used to talk to eBUS enabled heating systems. This is primarily Vaillant heat pumps and combi boilers. But Atag boilers also allow connectivity. You can purchase the hardware adapter from here (it ships from Germany) https://ebusd.eu/…

Tutorial from the geek [Tutorial: Heat Pump Monitoring using emoncms and Home Assistant (heatpumpmonitor.org)]

A pity he couldn’t get the name of the conductor the c.t. goes on correct. The c.t. normally goes on the LINE conductor. Both Line and Neutral conductors are regarded as LIVE because neither is necessarily at earth potential.

What tutorial / link did you use for the backdrop and positioning the data on it please ?

Didnt have tutorial. I drew the fridge circuit on another platform, saced as pic. And just used picture elements card on homeassistant dashboard. Its really not a good element though, looking for better ways to set it up. Ideally something that will save a screenshot of that picture at various tim…

Need to get some time and get a good look through that. Ive been away all week but have realised the heat pumps been cycling a load more than normal, whichbwent crazy last night when i upped the polling to every 60 seconds. So the ebusd adaptop appears to be significantly interfering with the ebus…

Ive managed to keep my system at a very low cycling rate so far. 3326 hours of compressor running time with only 911 starts (0.27 starts per hour) was 0.21 starts per hour before this week!) I thought i read the sheild c6 adapter wasnt meant to interfere with ebus, but as im forcing polls rather th…

It shouldn’t interfere, but at some point there was a home assistant related config that polled some problematic values and this led to the issues you describe. Which values are you avtively polling? Are you using HA?

Yeah. My thoughts too Andre I had this a while ago, overpolling and cycling. I’m gonna have to search back through the thread to find it. It was just a setting change in the end.
