use a timer after motion stops, 3 min works fine for me.
install the motion sensor at a good position where it is really able to detect every motion in the room.
A recommendation from my side is the HUE motion indoor sensor. With the newest HUE Zigbee app it works also as a occupancy sensor. But I think it is not useful for your requirement cause when you don’t move it will assume you left the room and will switch off the lights at once.
I like the HUE System feature of dimming lights in the end phase before it switchs off the lights. It’s like a warning which shouts MOVE or it will be dark in a minute
I will adopt this concept in my motion flows which trigger lights.
I read somewhere that someone had mounted a sensor in the waterbox. On the rod of the float. Door open, light on. Door closed, lamp stays on. Flush toilet, sensor contact is broken, starts a timer. When the timer is over, turn off the lamp.
If necessary, also set a timer of 10 minutes or so after opening the door so that the lamp goes of afterwards. If the toilet is not flushed.
I use a SonOff RF bridge that’s been flashed with Tasmota… I’ve also flashed it with the Portisch firmware to give it more options and flexibility.
I currently use flows to call up the MQTT client app to listen to , or send commands to the RF bridge. I will eventually probably use the Tasmota app once the developer has finished adding compatibility with it…
In an ideal world Homey could simply “learn” the codes from these very simple and very cheap 433mhz sensors without any fuss.
At this point in time though (unless Athom add RF learning) your best bet is to buy a Broadlink bridge. (No flashing required) …
Yes, it does suck but investing in 433mhz for your motion sensors is ultimately the best way to go. Even if you have to buy and add a Broadlink to your Homey you will save money overall . Also way less hassles with battery changes…
Anyone any experience with a 230V powered ceiling motion sensor based on Zigbee or W-Wave?
This to avoid batteries and use existing ceiling motion sensor hole.
