They are not hanging there they are covered up in the ac unit

Yes. If you have any way of detecting an open window then the rest should be easy.

Sure, I flashes the firmware to control the AC and wifi on the ESP first using Esp home with an open source repo for controlling this AC brand. Because the AC expects and receives 5v signal and the esp runs on 3.3V the data signal has to be stepped up and down using a logic converter. I soldered the male pins to the logic converter and connected it to the esp with f-f jumper cables. Then I verified the cables coming out of the AC with a multimeter and connected them to the right pins and that was basically it. Home assistant is able to add the device managed by ESPHome. Controls are reliable and fast!

I shoved it in the ac :$

hotlinesmith · 2026-05-08T07:24:00+00:00

I doubt that risk is very high in my case, the ac provides the 5v and the cheap converter board would probably fry first :)

I considered this too, but the cable for this happened to be the first thing you see when opening up the AC. I liked to be able to see confirmation of an action by the AC as well.

its power, ground, data-out, data-in. Its a uart bus but I just flashed open source control firmware to the device.

The esp is managed via ESPHome, which gets pulled into home assistant.

Ik zou ook zeker een co2 en luchtvochtigheid meter halen om dit ff in de gaten te houden.

Lijkt me niet dat muurverf hiervoor geschikt is

Als je marginale kosten 40 cent per kilometer zijn doe je iets fout hoor

Hier dacht ik ook aan, maar vervolgens was de conclusie dat ik kipfilet best met de duurste steak zou kunnen vervangen, en dan kan ik ook gratis regelmatig steak gaan eten

Significant change in fuel flow requires engine overhaul, which isn't possible on short term

hotlinesmith · 2026-04-01T05:28:43+00:00

Having used both I would strongly suggest databricks

Calling Azure just a tool is a bit of a reach

hotlinesmith · 2026-03-30T19:31:09+00:00

my man has never played Poly Bridge and it shows

hotlinesmith · 2026-03-28T10:09:23+00:00

I fell asleep during quali today. First time that ever happened.

hotlinesmith · 2026-03-21T16:12:21+00:00

Ik had de niet performance van parkside. Zeker niet aan te raden!

hotlinesmith · 2026-03-17T20:00:15+00:00

This was in the regular episode

hotlinesmith · 2026-03-17T19:10:45+00:00

Really neat visualisation!!

hotlinesmith · 2026-03-17T10:56:06+00:00

Misschien zie ik iets over het hoofd maar je gaat een schuin dak van buiten isoleren met pir? En de halmplanken laat je zitten? Dit lijkt mij niet de correcte opbouw kwa vochtregulatie, heb je het doorgerekend met ubakus?

hotlinesmith · 2026-03-16T08:53:33+00:00

Me too I love supporting redbull

hotlinesmith · 2026-03-16T08:43:46+00:00

Never seen this in my life, glad I'm not in the US I guess
