Ooh I need to do this. What fan did you use?

Here are the details :

140mm Fan Riser printed in PETG

Smart Plug from SmartPad. I went with the Tuya option even though it's controlled locally by Home Assistant

ID-Cooling AS-140-W 140mm Case Fan

12v Power Supply

*Very important. The 12v Power Supply is not stablized. If less current is drawn, there is a rise in voltage. Given the fan uses so little, that rise is substantial.* In short, set the power supply to 6V. It actually pulls and then sends around 10V to the fan. So the fan spins a bit slower than it could. But it's also more quiet.

Or just use a 12v power supply from an old external disk?

Implemented some Blueprints that Gemini helped me create.
Required some trial & error to get them working the way I wanted, but Gemini is pretty helpful.

Blueprints covering what?

I've found LLMs to be quite good at these things

Using my Shelly Presence Gen4 to determine if there is someone in the room, and if the room is dark enough, then turn on the kitchen or lounge lights for 3 min. Then turn them off.

any way to bring my electric fence into HA? I would like to see that the Joules are where it needs to be. Also power it on and off remotely. My understanding is that a smart plug won't work as you need the battery inside the energiser otherwise it won't work.

A bit of a late reply.

I used a Sonoff SV in isolated mode (the same way that it is used for garage door motors and electric gates). Energisers have dry contacts inside so you can hook up a few different things to them. I also flashed the SV with ESPHome so it intergrates without problem into HA.

1. The on/off dry contact is hooked up to the SV's relay which toggles on/off for a second or so to simulate the magnetic fob.
2. I hooked up the 12V siren dry contact to a 12V relay that I monitor on one of the three exposed GPIO pins for an alarm.
3. I soldered two leads to the status LED of the energiser and hooked them up via an optocoupler to one of the other GPIO pins.

The code and set-up are both very experimental and I struggled a lot with debouncing the status signal and getting the right toggle interval for the on/off switch, but the set-up has been working and stable for a year now. I want to fix it up properly in the next few months so it looks neater though.

If you want, I can do a proper write-up for you of what sins I committed.

Got to have serious patience to get Home Assistant working.
And then to make it even more frustrating AI's instructions do not match the interface.
Fook that **** to switch on a lamp

I did a fresh setup of HA after I received my Shelly Presence Gen4.
Gemini helped me do the automations and it was pretty simple.

Assuming this is a Nemtek unit... please do the write up
