alt Hacker NewsI took a Vornado TRANSOM, a Broadlink RM4, and a Shelly Smart Plug, a Qingping Air Quality Monitor Gen 2 + claude and HASS, and now I have a fan that turns itself on when the CO2 level gets too high.
And I can override or change it from Apple Home.
The smart plug lets it verify that the fan is actually running, (because it measures usage) and we worked out that after a power cycle the Vornado goes back to a known state, and we can find the speed by forcing it all the way to 4 and then stepping back.

Nice! I have a similar setup. You might like the custom visualization or temperature and humidity offsets I’ve made for that air monitor. Its screen and battery cause excess heat to throw off readings and the calibration is rough from the factory, I used a cheap bluetooth govee thermo-hygrometer as reference to build a better cal curve.
Small world, just submitted PRs to add Vornado Strata 433mhz decoder to rtl_sdr :)
Need to try to get Sonoff bridge rigged up next but have been busy messing with Hatch alarm
