You’re very welcome Axios.
As you indicated, this is very much a custom solution and there will be a learning curve but I’ll do my best to document everything (part #'s, schematics, Arduino IDE, Arduino code, MQTT etc.). The Arduino(s) will require a single MQTT broker for directional communications between each MEHVAC and the plugin. As I mentioned previously, this plugin was written entirely in Lua. With that said, I’m not using a Vera (too unstable and unpredictable) - rather I’m using openLuup and AltUI. Both of these amazing solutions can be found here on this website within the “Plugin and Plugin Development” section. This isn’t to say that the MEHVAC plugin wouldn’t work on a Vera, I’m just unable to test it.
MelCloud looks very similar (function) to that of Kumo Clound. I can only speak of the MHK1 solution I was previously using which plugged directly into the Mitsubishi CN105 connector. Point being, if the unit has a CN105 connector then this should conceptually work. The developers of the Arduino code are maintaining a list of known working Mitsubishi units…
I realize this solution isn’t for all but I was tired of paying the high cost to manage these units. After the release of Kumo Cloud, I’d have to ditch my previous solution and buy 6 of Kumo’s… I wasn’t about to do that so it was totally worth it to me to learn how to put this plugin together as well as the Arduino’s.
Hope I was able to answer all your questions…
[quote=“Axios, post:16, topic:193081”]Hi,
first of all: thanks!
I see, then a “custom” hardware interface is needed… but, given You have that interface and successfully connect it to the CN105 connector, after that? To have this connected and working, for example, to a VeraPlus HA sistem? I was thinking to buy (I am in Europe) a Mitsubishi Conditioner which can be connected to an “MAC-567IF-E” interface and, with that using wifi to the Net and to a system called “Melcloud”.
So, since this"MAC-567IF-E" interface itself connects to the CN105. So “all” that is needed is an “interface for dummies” step-by-step instruction of how to craft it and, above all, a guide to make it all works with the Vera(Plus) system… or some way for Vera to interact “cloud-to-cloud” with the “Melcloud” or “KumoCloud”.[/quote]
