Product: CN105-2HA controller for Mishubishi climatiser 253 sold

Everything's great, price is okay. One small caveat: definitely check beforehand whether the plug is actually this type/designation.

Hello, the delivery was quick and straightforward. The product was as described and works as it should. Unfortunately, my air conditioner has different connectors and I had to resolder them. Nobody knew this beforehand. However, there are numerous and detailed instructions online for changing the connectors. Thank you very much.

Nice products !

Very good product. I ordered two of them. Writing this comment, I just realize the documentation is on the product page, I missed it to use the current flash. It is sad that the solderings are below the adhesive making the lines unclear. I checked with multimeter and it matches perfectly with the flashed yaml.
Also I did not get the grey/black box ... Sad, because the free pins are dangerous.

Works beautifullh with my A/C

I can finally control my AC with home assistant.
One downside is that this doesn’t sync with my normal remote. If I set 24 degrees on my remote, then 20 in home assistant, it still says 24 on the remote. Pressing on the Down button on the remote then gets you 23. This is a limitation of the mitshubishi desgin, not something that is fixable, since the remote is 1 way. Not a problem for me, since I just add the climate card to my dashboard and control it that.
I didnt know what the default password was when it arrived, it didnt say it anywhere on the box, but after contacting the seller I got a response in like 10 minutes pointing me to a pdf document.

A great little device which changes out A/C unit

I have 9 Mitsubishi heads in my house, and I had been using z-wave IR blasters to automate their management. This little unit changes the game entirely: no beeping, no guesses whether the IR signal went through, able to rely on a room temperature sensor rather than the silly sensor inside the unit itself, stable communication, great support.
Highly recommended; honestly, I can't imagine anyone dealing with more than one Mitsubishi heads and/or having a need/desire to automate temperature management and not using these devices.
