I bought a Shelly 1, and wanted to replace a Fibaro FGS222.
I have a ‘normal’ 220V motion sensor attached to it. With the Fibaro, it worked fine. But with the shelly the input stays high always…
I have the following setup:
But instead of a switch, I have the following motion sensor: https://www.steinel.de/en/sensors/motion-detectors/is-130-2-silver.html
I did some measuring, and the Shelly 1 has 25 VAC on the ‘SW’, with nothing attached.
When I connect the motion sensor to the Shelly 1, and the motion sensor has no motion detected, there is 100 VAC on the ‘SW’.
When the sensor detects motion, there is 220 VAC, which is normal.
I opened the motion sensor, and there is a relay inside. But there are also some resistors and capacitors connected to the relay output. Maybe this might be the problem?
Has anyone a easy solution for this? Or maybe another easy way to get a signal from this motion sensor?
The sensor is outdoor mounted.
