Mitsubishi MSZ DM-25 about arduino-heatpumpir

[ToniA]

Try if it responds as MitsubishiFD or MitsubishiFE model. Take a look at https://github.com/ToniA/arduino-heatpumpir/blob/master/examples/simple/simple.ino, and remove everything else but MitsubishiFDHeatpumpIR from the heatpumpIR array (starting from line 35).

OK thank you, but actually i don't have the heatpump yet. My seller quote is for a DM-25 ... may be i should ask for a FD-25 to be sure i can control it in domoticZ ...

[ToniA]

I really don't know... It might very well work, or it might not. I have very limited experience with Mitsubishi units, all of the code and IR samples is contributed.

I'm buying the DM. If the control does not work (buyer told me the telecommand changes often ) i'll be interested in the retro engineering method used to decode the IR transmission protocol ... and for that may be i need to contact the people who did the job for the Mitsubishi FD ... (?)

Is there any follow-up on whether Mitsubishi MSZ units are supported by this code? I am interested in developing a controller that will automatically shut down the AC after approximately 9 PM and then turn it back on every morning. The Mitsubishi remote requires you to manually enable on/off control every 24 hours or it defaults back to the last mode (on or off) based on the mode the AC was in when the 24 hour period ends. I understand that I have to send a long string of commands, but it looks like the HeatpumpIR library will handle the string, I just have to add the ability to enter my desired operating temperature . Also if there is a simpler method to automatic daily on/off operation please point me in that direction. Thanks in advance for your feedback and this library that you have provided.
