Panasonic WH-SXF12D9E8 Heat Pump & ESP easy

[max100]

Good day,
I would like to control my heat pump "Panasonic WH-SXF12D9E8 Heat Pump" with the help of esp easy, but I am new to this. Can someone help?

Assuming this device is controlled using an infrared remote control, you might be able to send commands and possibly receive status updates using the IRremoteESP8266 library or HeatpumpIR library, that is supported by ESPEasy in the IR builds (best use an ESP32 as that includes most/all of the protocols, in ESP8266 some are excluded for size reasons).
You might want to investigate if your brand & model is supported there.
Connecting both an IR transmitter-LED and IR receiver to an ESP should probably get you going.

Good day,
unfortunately, it is not possible to control using IR, there is a controller with a display built into the heat pump unit.

Well, if there's no way of externally controlling the device, I don't know how to 'fix' that using ESPEasy...

I had a Wemos D1 R1 with some DS18B2o sensors, a relay on/off and a IR LED for controlling a heating device. Was some 2021 ESPEasy build, I did not remember which one. I had a firmware update to some 2024 build, the device reset to default, luckily I had a config.dat but I'm not find a build which support all my devices.
Tried with custom IR, minimal IR , no chance...
What's the right build?

There is also a number of special builds:
- normal_IR => "Normal" + IR receiver/transmitter plugins and library

Where is the normal IR ? ... could be this: ESP_Easy_mega_20240822_normal_IRext_no_rx_ESP8266_4M2M ?

Yes, that's the right firmware... needs to be flashed via serial, via OTA the system crashed

The build that comes closest to what you need would be "normal_IRext_no_rx_ESP8266_4M2M", but that has the disadvantage of having a different flash layout, so you'll have to take some precautions before starting the upgrade, as the config will most likely be reset (again?) when upgrading to this build with different flash layout (4M2M instead of 4M1M).
- Use the Tools/Backup files button to create a .tar backup of your current setup, be sure to have the browser save the file, as they seem to think you shouldn't save a .tar file (silly browser ) (or you can use the older config.dat backup you already used)
- Install the normal_IRext_no_rx_ESP8266_4M2M build on your node (possibly it already has the configuration, as I suspect you have been using this build/flash layout before...)
- If it doesn't connect to the WiFi automatically (the current WiFi settings are saved in non-volatile storage (NVS), and are used when no settings file can be found), or use the AP feature to connect to the WiFi
- Check if you have any devices configured, if it's all back, then all is fine
- If no devices are configured, restore the backup you created (or the config.dat you already had). The .tar file must be restored without renaming to config.dat or the restore will fail! Reboot immediately afterward, using the button that's shown.
- Check if all devices are present, I expect them to be all there.

Did a serial flash with 4M2M build, loaded the config.dat file and everything is back. Of course the rule which I have it on plain text, saved before. And the password on the mqtt controller...
