So when the beam is broken, it’ll close the volt-free NO contacts. I need a Zwave/Zigbee module that I can wire this into (to fire the event in ST itself) - I’m thinking of hacking apart an Aeotec Panic button and soldering the output to the button contacts, but I’d prefer a proper module if such a thing exists. Is anyone aware of something that I could use for this (in the UK)?
This guy has the same idea:
But the sensors he’s using (Schlage RS100HC) aren’t available this side of the pond.
Easiest way is either a Fibaro door sensor with dry contacts or…
The thing that I use all the time, a water sensor
Just cut the plug off the sensor and connect across your n/o contact
When the contact closes the sensor shows wet
Recently Maplins had them on offer but not sure that they have any left
