Outdoor motion sensor

[henkc]

I have a bunch of outdoor lights connected to a Sonoff switch, as well as some which could/should be. Are there outdoor motion sensors which could be used to switch these on or off? From what I can see, the Sonoff motion detectors aren't rated for outdoor installation.

I had 3 of the older, rectangular Sonoff sensors installed outdoors for a couple of years in a very harsh coastal environment, they're still working now but on a different property. I just sealed the battery compartments with insulation tape wrapped around the body of the sensor and then some craft adhesive around the edges of the lenses. You do get a plastic "rain/sun" cover specifically made for these sensors, check on Ali Express.
Edit: You'll also need the appropriate bridge if you take this route

You can use your alarms motion sensors if you integrate the alarm into HA.
