Too rich for my blood. That would be a lot of devices to replace.
I’ve got a mix of Ikea Tradfri, Sengled, SONOFF, and ThirdReality Zigbee lights and switches.
I have my Tradfri bulbs set to remember their previous state, but that appears to only work if you are using the Tradfri gateway.
I had a solution that worked when I was running Hubitat.
I never bothered connecting ST and Hubitat since the tool that links them requires Groovy, and that’s going away at some point soon-ish.
I’d love to see something similar available like what you can use to connect Hubitat (Maker API) and HA that stays all within your local network.
Not sure if the ST folks plan on making the platform totally cloud-free.
By the time the afternoon routines were set to activate, everything was working as expected.
