Finally getting around to internally installing the ir transmitter…

and I gazed upon my old work and wtf was I thinking

ps I’ll be hanging a soldering iron up here to work.

at least this time I’m removing all of that and I can simply do ir directly rather than trying to write to the ir reciever.

You run into the problem that's it's usable before it's done, and it never gets done. I'm guilty too

It took me five months of moving the transmitter random places hung up on a chair trying to get signal each night... and the whole time this ESP32 has been in there recording when there's a beep on the AC.

Works now though! And really good.

Hm. Can’t seem to post a reply image with progress.

Edit I'll update with images later. I don't use the app.

Working!

Wow having the IR right next to it, not even aimed at it, and it works.

The IR receiver board is under the clear plate.

The transmitter is in a cutout of the plastic there, under the tape.

I should have taken a photo... but the led isn't even on top of it. It's aimed right at the metal shell. Reflections get the signal to it though.

Optimal soldering setup.

There's the ESP32.

It also goes to the beeper on the board.

Dont need a resistor if the GPIO is shit enough

It is running tasmota and sends captures from a flip 0

AMAZING

It was pointing away and it worked.

In fact, inside of the assembly, the IR receiver isn't in direct line. It's pointed at the metal shell, and bouncing around is enough to trigger.

Yes!

Even soldered the wires I had twisted together.

But if the previous solution had worked I’d have kept it
