Gonna re-post my guide for anyone with a Mitsubishi Electric split-system Air con from the last 10ish years, on how to integrate it with Home Assistant/ESPHome for $20 with one extremely easy, reversible, safe hardware addition!
I've been running it without issue for 9 months now, and others have successfully followed my process.

github.com/echavet/MitsubishiC

Original post here: cathode.church/@s0/11350920957

I've used the integration to do stuff like automatically turn off the aircon an hour after I go to sleep, and put an automation so if we leave the house, it'll turn the aircon off in case we forgot. I also built an automation to run it in fan only mode on low for 15 minutes after being on cooling, to evaporate the moisture inside that otherwise leaves to building up mould.

Wanted to note how extremely easy it was to get this working with the M5Stack NanoC6 and one HY2.0-4P cable from them. By coincidence the pinout lines up exactly with pins 2-5 of the Mitsubishi CN1...

I wonder how many signatures we could get for an EU initiative that would require manufacturers to sell same quality "dumb" counterparts to their regular "smart" offerings of appliances and electronics, at the same or lower price.

Dumb TVs, washing machines, coffee makers, toothbrushes, etc. that would not require apps, wifi, bluetooth, phoning home, ads, etc.

Remove anything extra that is not required for the core use case of the product.

We have another addition to our Works with Home Assistant program to share - Zooz! 🎉

They bring an awesome selection of device types and certified the first Z-Wave devices in the program this year. 👏🏻 Learn more about what devices they certified in the latest blog 👇🏼

OK, so I got some preliminary results. I used this video heatmap tool.

My video was pretty crappy. The camera wasn't well placed. But it's kinda neat for a first attempt.

There's a couple hot areas at the top left and bottom right. The top left is a spillway in the pool that has water constantly moving. And I think the bottom right is just grass/bushes blowing in the wind.

I took the video and compressed it down quite a bit, so it's an hour's worth of motion in 20 seconds. Pretty neat.

It did confirm my suspicions that the robot gets stuck in the corners a lot and doesn't do a lot of longitudinal runs. This is only the first hour out of 3, though, so it's possible it did more later.

Ok. Here's a 10-second sample of what I got. 3 things went wrong.

  1. The gopro has some "automatic" get-the-orientation-wrong sensor. It decided this was a portrait mode video.
  2. It's impossible to see, from the ground, what the video looks like when it's all the way up. So it's not really focused on the pool well. There's a whole chunk of pool excluded.
  3. I only got about an hour, but the poomba battery lasted 3.5 hours. I have power I can tap, so next time I try this I will plug the camera in.

Still, I have enough video to experiment with. I also need to see whether the wide-angle lens is necessary, or whether I can get it with linear focus instead.

I'm curious how much it gets stuck in the corners. Unlike a lot of pools, there isn't a straight line in my pool. It's a curvy, asymmetric shape. Some of the curvature is obviously the fishbowl effect from the lens. But there really aren't any straight lines.

Second round, this time the #HomeAssistant on my #RaspberryPi4 - I still had a 32-bit install and it was time to migrate. Support ends this year and #ESPHome already couldn't be updated any more.
It was relatively easy - create a #backup on old system, boot a new install and select #restore on the setup page.
It took a while to restore everything, and I got impatient, but after around 30 minutes it was finished and everything like before.

I suspect my RasPi does not what it is supposed to do because it runs out of power. This is getting so out of my own comfort zone 😿

First it works as it should and after a while it ... does everything else except closes the relay to trigger door closing - which is The Reason why it exists!

I guess next thing is to switch it with my other, more capable Raspberry 3, 4 or 5 with the current Zero and try with a new hardware and maybe bigger phone charger.
