I’ve finally managed to get one of my systems hooked up using a direct serial connection using this Arduino sketch running on an ESP32 which is now reporting in via MQTT → Home Assistant → Emoncms. [image] GitHub - rbroker/ecodan-ha-local: Local HomeAssistant support for Air to... Local…

or Just don’t juse 12v at all, it’s not needed. Use the 5v from the cn105 to power the esp. you probably got lucky this time.

Please forget my question. The issue was a bad contact on the connector Tx pin. Thanks for your answers and your support.

Hi, My indoor unit has 2 boosters, one 3kW and one 6kW. @F1p Is it possible to add a 2nd booster to Mitsubishi Ecodan Bridge? I only see the 1st booster (3kW) when gets activated. It would be nice to see them both running. Depending on the necessary heat, the 1st booster gets activated or the secon…

@gregory75 - Yes i would love to! Would it be possible to provide a telnet export while the booster is running so i can be sure we are identifying it properly (maybe in a DM)

A big THANK YOU! @F1p I can see both boosters now. I don’t feel like messing with the heat pump right now, but tomorrow night we will get -20C so i know that both boosters will be active. Will report back. Update: Working as it should.

cool did not know it was possible, also added support for it in my esp impl.

I just found and implemented the total increasing energy consumption according to the heatpump. We now have ‘realtime’ sensor for it. It can be useful to ppl without energy meter to get a better understanding of the consumption. [image] GitHub - gekkekoe/esphome-ecodan-hp: ESPHome Eco…

This is a FTC6+ only parameter for awareness

I’ve added a ‘realtime’ consumption counter that uses the newly found numbers (ftc6+ only). It’s pretty useful when you don’t have a kWh meter. It now also calculates ‘realtime’ COP using this data (ftc6+ only) for ppl without a meter. You can use this to find the range of power output where your h…

Mitsi has a new app with a new BT dongle to cn105 for installers. It can send service request codes over cn105 and thanks to an owner of this device I received logging via our proxy mechanism. Been working on this with @F1p btw. I’ve added support for request codes and the following sensors are now…
