    Does anyone know if its possible to read the heat pump / AC's reading of humidity (like we can for temperature) using these methods?

    Hi David,

    I'm sure it likely can communicate with an RF24, we don't currently have stock of these, we do have this one if that helps:

    Adafruit HUZZAH ESP8266 Breakout

    Hi
    This looks like exactly what I need. I have been using Arduino boards with RF24 wifi modules to talk to each other. Can my RF24 communicate with the HUZZAH board?
    When will they be in stock?
    Regards

    This product works some of the time. If you have mains voltage through two relays at once, after a period of time the board shuts down.There is a warning about in on the seeed web page for this item.

  17. Josh Lobel - Sunday, 21 June 2020 on blog post Hacking a Mitsubishi Heat Pump / Air Conditioner
    Thanks to everyone, and especially Hadley for all of this work.

    I have pursued the Raspberry pi approach, and have most things working. I can use mitsi.py to change settings on my MSZ-FH12NA. I was initially confused by the TX and RX connection - not realizing that I had to connect TX on mitsubishi to RX on pi.

    However, I'm not sure what to do with the mqmitsi MQTT file. I have downloaded mosquitto, and can read publish and subscribe messages, but they don't seem to write/read from the serial port. If I issue a pub command like

    mosquitto_pub -h localhost -t "heatpump/command/state" -m '{"power":"ON", "temp": 15, "mode": "COOL"}'

    it doesn't change the heat pump.

    Do I need to do something like :
    python mqmitsi &
    to run it in the background (i've tried that), or do I need to add it to the mosquito broker in some way?

    Thanks for any advice. I have not installed home assistant yet. I'm using Pi Zero W to control the heatpumps and they don't suggest installing home assistant on the pi 0.

    It's not. Unfortunately we don't have that specific connector currently.

    Is this the connector to use for the Mitsubishi heat pump project ?

    If someone is interested to control his/her Mitsubishi air conditioners via Samsung SmartThings feel free to check my project:

    https://github.com/JMan7777/Mitsubishi-Aircon-SmartThings

    It uses an ESP32 connected via the CN105 port and the SmartThings Classic app.

    That's sounds like a great system. Is there any chance that you post your Software for the Arduino? Is it possible to buy it somewhere? We are a small milking farm. The milkling company offered us 78'000 to replace the milking system controllers. That's more money that we will do in a full year work.

    Thanks!

    Wouldn't recommend these, I bought 4 and 3 of them started leaking voltage through on the load side, my lightbulbs would flicker when the relay control was disconnected and work correctly when powered on.

    Hi,

    Can somebody to clarify pinout of CNS connector for MHI?
    According to project of Rob Dekker https://github.com/rjdekker/MHI2MQTT:
    Pin 1 (left) = 12V, pin 2 = SPI clock, pin 3 = SPI MOSI, pin 4 = SPI MISO, pin 5 (right) = GND.
    But when I looked at some recent project (which based on Rob's one) https://github.com/absalom-muc/MHI-AC-Ctrl/blob/master/Hardware.md
    pinout is different:
    Pin 1 (left) = 12V, pin 2 = SPI MISO, pin 3 = SPI clock, pin 4 = SPI MOSI, pin 5 (right) = GND.
    Personally I have SRK25ZJ-S, a board a little bit different, but it also has CNS connector. So, before try to build WIFI MQTT bridge with ESP8266 I would like to clarify pinout for AC connector.

    Thanks in advice!

  46. Just wondering... - Friday, 01 November 2019 on blog post Hacking a Mitsubishi Heat Pump / Air Conditioner
    Hi! Nice hack! I have messed about with the MSZ-FD25VA with a remote marked as KM09D and one thing in the manual baffles me:

    "After you turn the breaker ON, the first remote controller that sends the signal to the indoor unit will be regarded as the remote controller for the indoor unit.The indoor unit only accept the signal from the remote controller that has been assigned to the indoor unit once they are set.The setting will be cancelled if the breaker is turned OFF, or the power supply is shut down.Please conduct the above setting once again after the power has restored."

    Does this mean that there are some type of id sent on all KM09D remotes, or does this just mean different model of a remote? I haven't found out any indication in the IR-code. What else? Oh god... different timings on the hi and low states of the pulse!? I have a working control unit which just emulates the remote, but it seems that it sometimes doesn't work as intended...

    If anyone is trying to make setting remote temperature work and just getting roomTemperature reported as 10, you might want to check out https://github.com/SwiCago/HeatPump/pull/144. This change allows things to work with my European MSZ-FH35.

  49. Michal - Sunday, 13 October 2019 on blog post Hacking a Mitsubishi Heat Pump / Air Conditioner
    @TimR Having the unit turn off was my initial plan. I was just a bit worried that there might be some additional wear and tear from doing that all day. Plus I believe there is a 3 minute delay between when the units turn on and the compressor can come on again?
  50. TimR - Sunday, 13 October 2019 on blog post Hacking a Mitsubishi Heat Pump / Air Conditioner
    @Michal Really if you're going to put an esp8266 in, you could just have the unit turn all the way off when the set point is reached and not bother with the resistors. Then if your remote goes down, the unit would fall-back and work with the internal sensor.
