Nadchodzący czujnik obecności Meross MS600 zgodny z Master wydaje się być interesujący. Nie potrzebuje baterii, wygląda całkiem nieźle i nie należy do najdroższych.

Hey #HomeAssistant bubble, I think I need your help.

I use this #Linptech #PresenceSensor via ZHA: https://www.linptech.org/24ghz-millimeter-wave-radar-human-presence-detection-sensor-wall-mounted/

I know it's not fully supported but until a few weeks ago it worked pretty much perfect. Then it started to detect something sometimes when nobody is there.

Now it looks more like the screenshot. Over hours presence is detected even when nobody is at home.

If I unmount it and cover it with something nothing is detected so the sensor seems to be "fine".

For extra context: it's in the kitchen and "looks" in the direction of the window. Nothing has changed in this room before the problems started to occur.

Screenshot of Home Assistant. The presence sensor shows occupied over long stretches of time and then randomly not anymore.

I'm looking into #mmwave presence sensors but I'm wondering about the (possible) health effects. Is anybody aware of any? I know we are exposed to radiation everyday (wifi, electronics, tv, radio, cellphone, etc.) but I'm wondering what a presence sensor could mean or if it's all neglible.
I would like credible sources, doesn't need to be an academic study but someone/something with knowledge on the subject.
