esphome-mitsubishiheatpump VS echonetlite_homeassistant

Controlling Mitsubishi mini split heat pumps instead of paying hundreds for Mitsubishis solution: https://github.com/geoffdavis/esphome-mitsubishiheatpump

DIY Plug in: this Github Project describes a way to diy a plug in connection running on ESPhome for a few $ of parts, but I'm a bit of a novice and don't know how I would connect this to Homekit.

If you Home Assistant or ESPHome, this is the jam. https://github.com/geoffdavis/esphome-mitsubishiheatpump

Highly likely you're experiencing a watchdog error on an idle core. The only way to know for sure is to enable logger, which will be a challenge here. You can see an example here., but this is a widely reported and poorly understood issue.

If you can add homeassistant, you should look at https://github.com/geoffdavis/esphome-mitsubishiheatpump -- we're using it with 5 split units. It works great, is faster than infrared, and cheaper than the wired or wireless control options from Mitsubishi.

If your Mitsubishi uses IR for it's remote, this probably would work: https://github.com/geoffdavis/esphome-mitsubishiheatpump

Or, you can use a Broadlink IR blaster to clone the remote.

If your heat pump talks to MEL cloud (Mitsubishi's cloud thingy) then this should work: https://www.home-assistant.io/integrations/melcloud/

I have yet to buy a "smart" device that I haven't been able to control through HA. The Broadlink RF/IR bridges even makes anything with a remote automatable.

Seriously, If it wasn't for Home Assistant, the "smartness" of smart devices would be next to useless.

I enabled echonet lite and use https://github.com/scottyphillips/echonetlite_homeassistant It’s great, and local too. You might have to build automations for some of the features you’re talking about but it can control every feature of my units.

If your aircon is HEMS/echonet lite compatible you could control it directly through home assistant. My aircon does, so I'm controlling it locally using this custom component (also got my solar system and hot water system working through it!).

Depending on how deep you are going with smart home stuff, any Japanese aircon that is listed as "HEMS" compatible, will also be echonet lite certified. If you are using a smart home hub like Home Assistant, you can install this custom component, enter your aircon's IP address, and it should just work (at least it did for my Toshiba aircon). It's all done locally, so if there is an outage with amazon aws or whatever servers the company use, it doesn't affect you, and you can set up home assistant to be accessible from anywhere and can use an ios or android app to access it. It also allows you to actually make a smart home, not just a remote controlled home.
