Hi,
I’m looking to add a limit switch to my driveway gate.
The gate is a horizontal sliding gate. Using a sensor I want to check if it is open or close.
My idea is to use a SONOFF SNZB-04 which I have, connecting some wires and linking it to a limit sensor.
The basic use of the magnet does not work as there has to be a minimum distance between the 2 sensor parts (2cm) to allow the gate to slide.
And it seems this is too much for the out of the box working of the sensor. The same issue exists with all sensors that use magnets.
Does anyone has any experience with a good (affordable) limit sensor that can be connected to the Sonoff ?
Requirements would be :
- water proof (IP65)
- works with the Sonoff (3V)
I’ve found different sensors, but the mention other voltages so I’m not sure they will work.
Example:
I would prefer something with a spring, as this is easier to install.
Any advice would be welcome !
Thanks
