I am in the middle of a house renno - and will have access to everything soon at frame stage. Im following this guide well:
Just wondering with contact sensors - i’ve always used zigbee batteries. And don’t have the need for home security system (as im using frigate etc with HA)
So what should I hardwire that isn’t in that guide i.e contact sensors - it seems the only options are a hardwired security system that would integrate to Home assistant?
If you wanted to hardwire some flush-mount contact sensor into your doors and frames, you wouldn’t necessarily have to connect them to a security system. You could just connect those wires to any smart input device. Off the top of my head, you could use something like the Shelly Plus i4, which detects up to 4 switch inputs.
