ESPHome Mitsubishi Ecodan and remote thermostat integrations

Maybe I’m not explain myself properly about the thermostats, so I attach photos to clarify.

With these thermostats, should I not need to manage the shutdown? and would it make sense/be advantageous to use HA feedback entities?

I’ve been testing without my automation and I observed:

  • When temperature exceeds ~1°C above setpoint, the compressor stops
  • But the climate entities in Home Assistant still show “heating” mode (not off)
  • After a while, the compressor starts again (even though temperature hasn’t dropped)

This raises me some questions:

  • Why does the compressor restart if temperature hasn’t dropped? Is this normal cycling?
  • Should I use Server Control Prohibit to fully shut down the system when compressor stops?
  • Does the “Auto-Adaptive: Room Temperature source” setting affect this ON/OFF behavior, or is it only for the flow temperature calculation?

As for the flow temperature, I was just doing some tests.

My doubts were more related to the calculation, since I understand that the error decreases as the temperature approaches the desired temperature, but it seemed strange to me that even so, the flow temperature calculation was higher than the maximum, considering that it wasn’t very cold either (cold_factor: 0.03).

Many thanks and sorry for the disruption

no correct those are wireless thermostats and they should generate stop condition.

It’s a known ‘feature/issue’ that the CNRF thermostat (wireless is one of them) is having +1c overshoot.

You did have a buffer tank right ? Then there might be heating demand on the zones, but the tank has enough heat and compressor does not need to operate.

But its very difficult to trouble shoot without logs. Record them via esphome-ecodan-hp/docs/faq.md at 70442bb6e3b51f4c1b37f32f07a0e4b59ea2d8a3 · gekkekoe/esphome-ecodan-hp · GitHub and post them in a new question on github discussion section

Headsup: it’s also now available for for UK based users.

I seem to have found a bug of sorts. When the controller gets fully disconnected from power and then turned back on, it adds 65535kw to the used energy.

Which sensor exactly ?

thanks, it’s fixed to the next release
