Making AC free from Chinese software

[silk ether]

I'm planning to make my Be Cool split air conditioner

independent from Tuya and integrate it locally into Home Assistant via an ESP C6.
For this, I'm using the following guides:

Does anyone have experience implementing this on an ESP C6?
I would like to purchase the following for this:

I have no idea how to start xd

will be the same advice for all your other projects, including this one: If you are not shure how to handle electrical circuits, keep your hands away from it and get help from a sparky!

That is not really a problem. But i want to know if it is possible

Is the Tyua controller plugged in via USB? If so, something like this MIGHT work for you and you wouldn't even have to roll your own. https://cloudfree.shop/product/ductless-hvac-wi-fi-module/

My mini-split is a Mr. Cool brand (not on their list), but AIUI, the Midea brand standard is pretty widely used and many different brands are compatible with it. For only $13 (YMMV) it might be worth a shot if you're not sure.

(NOTE: I purchased 2 from this seller before and have been very satisfied with this purchase and others, but have no affiliation. I'm sure the product is available from other retailers.)

Also, just noticed this: https://discord.com/channels/330944238910963714/1448497633105547304 someone posted about in this Discord

Nice

I do not know if it is via usb tough

[tough notch]

IMHO, it's worth checking out. The first one I posted has worked a treat for me. The only difficulty I had was physically installing the dongle - the USB port was buried so far into a housing I had to remove & disassemble quite a few pieces to get it plugged in. Once I reassembled & turned power on, it just showed up in HA.

In your last pic, you have 2 boxes--1 white wire, 1 black wire held on the lid with a single screw. One of those probably has a "USB" port in it. iirc it looks like USB but is actually something else

[silk ether]

You mean this?

I think it is the beeper if I am not wrong

[tough notch]

IMHO, it's worth shutting off the power to the unit and opening the two of them up to see what's in there. If it's a USB port, it's likely that there's a very simple solution already made for you.

[silk ether]

Yeah thank you I will try to find out

So you mean turning off the power completely?

Like the safety switch

[modern ruin]

yes

[tough notch]

Absolutely!
Cut power to the whole unit. Either unplug it from the wall, or, if it's hard wired, turn off the breaker (unscrew a fuse) in the panel, or, in the US at least, there's a requirement for there to be a disconnect switch within site of the outdoor condenser unit - you can turn off power there, instead.

If you don't cut power before working on it, you might accidentally short something and damage the AC unit or worse, hurt yourself.

Always cut power before working on electrical things!

I have like a switch in the kitchen room for all rooms in the house

[tough notch]

The switch turns off all the Heat/AC units throughout the house? Flip that off.
If there is anyone else in the house, tape the switch in the off position & put a label on it saying you're working on it, do NOT turn on, you might electrocute me!

I mean the fuse for the room I am in.
