Hi,
I have Yeelight bulb in my bedroom.
I want to turn it on whenever someone enter my bedroom (I was thinking by motion) and I need a motion sensor for it.
Anyone can suggest on a cheap / compatible Wi-Fi / MQTT motion or any other sensor that can help achieve this goal easily?
I personally use HC-SR501 and HC-SR505 sensors on a Raspberry Pi that talks to HA via MQTT.
Opted for this because it does not require batteries (wired to all needed locations)
Works great,
But you need the sensor AND a Raspberry pi in place, so you are wiring a raspberry pi and motion sensor when you need to detect motion? I will end up with a raspberry pi in every room, it feels bad (and a lot of wiring in every room as well)
nope, I have a single Pi and lots of motion sensors (7 so far).
I just run the cables (recycled cat5 ethernet cables) to all needed places.
I also use a logic OR gate when the room is too big.
