The lesson I think is only buy devices with local apis and avoid google services entirely. I have tons of smart devices in my house now but I require local control and they all sit on an isolated VLAN with no internet. The nest is the last remaining device that I haven’t switched over yet. Its 8 years old, I didn’t think about any of those things 8 years ago. Live and learn I guess.
