Does anyone know if there's a good algorithm for automatically controlling ceiling fans? Like if it's hot and the room is occupied, turn it on duh, but something with the "feels like" temperature might be better?
Maybe have a temperature sensor at ceiling height and floor height and do something with those? #homeautomation

Does anyone know a USB camera which has focus (provides sharp images) starting at 2cm maximum 5cm distance from the front of the lense?

Not a webcam, more for tinkering, like ebay.de/itm/176974679649?_skw=

The data in the usual webshops hardly mentions this technical data.

Background: I want to try some OCR on a Ferraris power meter. (I have the led based method detecting the pass of the red bar. Want to try OCR now.)

July has been jam packed with new additions to the WWHA program - for this month's final addition, Shelly is joining! 🥳

They certified Z-Wave devices like their retrofit smart switches & relays, turning dumb devices into smart ones. 🙌🏻

Check out the blog for more details 👇🏼

Yesterday I noticed that the pool pump wasn't running. I checked the power consumption logs and found it hasn't been running for a few days. This is very bad! High risk of soup pool.

After fixing the issue with the pump, I set up an automation in #homeassistant : At 09:30 every day, check the power consumption of the pump. Send an alert to my phone if it's less than 1.5kW.

All thanks to #foss!

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.

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.
