Hi there! Is there any way of using a specific binding in order to connect AC units of Mitsubishi through “MELCloudHome” instead of MELCloud? The app of “MELCloud” is really old-style and I would love to use “MELCloudHome” but these are two separate instances of Mitsubishi. I had to register at “ME…

[image] germany_phil: MELCloudHome From what little I can tell, it’s a wholly separate API meaning it will require a wholly new binding (or major additions to the existing binding). There is at least one third party library on Github that could be used to create a MELCloudHome2MQTT type side…

Cannot guarantee it will work, but try this binding that I started developing . Tl;dr: some wifi modules in their heat pumps have a local api which can be used, skipping cloud completely.

Works great with my AC! Thank you!! I have seen in another threat that we almost got the same unit. I have the LN60 version. The only thing is: I get dates for the items “fan speed” and both vane settings. Probably I have to use a certain format for these items in the items file.

Of course it wasn’t. :see_no_evil_monkey: It was a String. I used the items file from the previous binding in order to avoid re-creating all items and the sitemap. Little change and format is correct now. Thanks again!

Thanks for updating the binding and your perfect timing. Just got an Ecodan Air-to-Water (ATW) heatpump installed with the new WIFI module that only be used with MELCloud Home. Everything works great except for the ‘outdoor-temperature’ that continuously shows 0ºC, any idea what can cause this?

The trace message is quite long but it contains the ‘OutdoorTemperature’: {“name”:“OutdoorTemperature”,“value”:“0”} It is defined as “0” while the temperature is 22ºC. If you need the complete message please let me know .
