A couple of light bulbs burnt out and I want to replace them with bulbs that I can use exclusivity on Home Assistant and bypass the manufacturers app entirely. What brand should I look for?
Bulbs that work via Zigbee instead of wifi. I use ThirdReality's zigbee RGB bulbs. $30 for a 4-pack. They do the thing. You'll need a Zigbee adapter, too; Nabu Casa sells one that works well.
replacing Google Calendar and Keep Notes with Home Assistant
Could you elaborate on this a bit?
