I am looking for an Aircondition (Heat/Cool) can be controlled completly (heat /cool/and level) by HA.
I am asking because I want to use my additional electrical energy from my photovoltais to heat/cool my house. The device should be available in Germany.
I second the Broadlink RM4 solution, if you donāt want to recable or purchase a whole new system or thermostat. I used to have my previous rented home AC controlled thorugh broadlink. It takes some time to train all codes, plus you donāt have a ācurrent stateā (you need to derive it from the actions your perform through HA), but otherwise very versatile.
Now i switched homes and my cheap landlord has thisā¦ https://manualzz.com/doc/63886127/watts-industries-ecolux-04.07.605-instructions good luck integrating that.
Newer Mitsubishi equipped with WiFi module works through MELCloud integration.
There is, in mine opinion, just one annoying thing:
If I change something via remote, it takes around minute to see change in HA, and if something changed via HA remote never get update. But I can live with that.
Smart aircon tends to cost a pretty hefty premium over non-smart. I use the SmartIR HACS addon with a Broadlink RM4 Mini and it works very well. Obviously it doesnāt sync with the airconās remote, but I never use that any more anyway. There is a fairly large list of supported aircons here.
I also use SmartIR with a broadlink, as the AC is a ādumbā oldyā¦
But, as mentioned, no feedback, so if the AC misses an IR command, HA wouldnāt know about it
So i prefer to use the EspHome module, easy and works flawless on my 2 other ACās
Mitsubishi via MEL cloud too. But in oposite direction, because my mitsubishi AC have āsmartā remote with display, it memorizes state of the AC and when is something changed via cloud, remote donāt see change. Not very important, but annoying.
Well, it is almost two years later now and I have currently the same question as Thomas stated in Sep. 2022. Now almost all new current available ACs are āsmartā and can therefore be controlled by browser/web/app. But which of all those work well with HA? Any current recommendations for the German market? I do know that there is a well maintained list of working Integrations - but that does not list a personal recommendation. Using a remote ESPHome IR is an option but as I buy a new AC, I would prefer an API connection so I can read settings and stats as well.
You can get a lot of branded Midea A/Cs in Germany, or if you are suited for that, in one of the EU markets, like Italy. There you can get even better prices.
I ordered my Olimpia Splendid via a german supplier, labeled with their name. Quite happy with it, and ESPHome is so much better than the provided Wifi-dongle from Midea.
You ask for the requirements. Well, I need to cool 3 rooms and therefore 1x3.5kw and 2x2.5 kw. They need to be low in noise but can be high in power consumption.
And the main requirement is - they need to be accessible in Home Assistant but please without the need to open them on the first day to modify the hardware.
Thanks for the link to the supported AC brands. However, it is not really my intension to buy brand new and then fit an esphome module inside the new AC as that will most likely end my warranty for the device on that first day.
You really, really need to inform yourself better, really. Itās not meant rude, but all your questions, and worries, are already answered quite often, not only here in this topic.
All this here works without interfering with the A/C unit. What you actually do, is preparing an USB dongle with ESPHome and put that in your unit. Depending on how exact you did the work with your dongle, it is something between putting a USB dongle into a USB port and not use the USB port, but the cables that are connecting it.
In the end, youāre doing exactly, what Midea (or whatever brand) does. Youāre connecting a Wifi dongle with the unit.
There is no chance, youād void the guarantee! Period!
Take a look at klimaworld(.)com and look for their own branded units.
well well, that does sound like a valid idea. So that is a working solution for Midea and similar models. But what about the other big names on the market (Daikin, Mitsubishi, Panasonic ā¦) do they work similar best with ESP32 or are there other solutions?
