Description:
Took me a long time before posting this issue.
Nor could i find the answers or similar issues over here.
Be kind on debugging this one

Since July 2025 i own a couple of Mitsubishi Heavy Industries air-conditioners.
1x - Mitsubishi heavy SRK50ZS-WF split unit 5kw with WiFi
2x - Mitsubishi heavy SRF25ZS-W 2,5kw wall converters with WiFi

Since owning them i enabled the hardware pluging Mitsubishi WF RAC Airco with LAN (HTTP) interface for each airco, so three in total.
I can control all three units via Domoticz so no problems on this side.
But every day i see a couple of times some error in de Domoticz UI Log Tab for each device.
These error messages happen randomly.
Sometimes a error which says hardware thread is ended but also the ones posted below.

Error: Woonkamer_Airco: Error executing HTTP command (getAirconStat)
Error: Slaapkamer_Airco: Error executing HTTP command (getAirconStat)
Error: Natalya_Airco: Error executing HTTP command (getAirconStat)

I really don't have a clue why they happen and how to solve it.
I'm not panicking as i still can control the airco's but the error is a bit annoying
Also not an expert on this one so hope someone has a solution or knows why this happens.

What i already have done to solve it:
Installed a fresh and bare Domoticz without any devices just only the RAC hardware modules enabled.
But didn't solve it.
What i'm trying to do now is uninstalling the Mitsubishi app from my phone to see if it's due to conflicting user login sessions.

The issue is that sometimes it looses its wifi connection.
Nothing you can do about it

If you really want to, there are ESP32 projects to control the aircons, or you can buy a zigbee IR controller and place this near every aircon.
