Making the AirGradient DIY

I’ve been working on getting air quality measurements going in and out of my house, however there are a lot of cloud connected sensors out there. I wanted these to be all local, though I wouldn’t mind adding to the public datasets for air quality. I ended up coming to AirGradient as the option that I decided to use, these use all open hardware and can be flashed with the custom AirGradient firmware, or with EspHome. I went the DIY route as well to save some money (and I’ll be customizing them a bit too).

Setting up Giscus Comments on WordPress

This blog was setup originally in 2016 and has never had a really useful comments section. There was a time when the only thing showing up were trackbacks to malicious websites.

I ended up on the TasmoAdmin addon for home assistant which provides the ability to update devices in bulk.

I’ve started using it combined with in order to part out wooden boxes and position them onto sheets to try and maximize the number of boxes fitting.

Z-Wave Firmware Updates in HASS

I may be a bit late to the story, but home assistant now has the ability to update Z-Wave device firmwares. This is good for keeping IOT devices more secure and eliminate bugs in the devices. The updates show up in the same list in the settings menu as add-on upgrades and home assistant core updates.

Z-Wave Firmware Updates in HASS

Though there isn’t much in the update details for my GE switches, the update did improve the responsiveness of the physical switch, now button press to light change is much faster (minimal lag) than before the update (maybe 500ms lag).
