For controlling the lamps at home I am using some Fibaro motion sensors. They are driven by batteries but the life time of the batteries is to short and I would like to change them to a motion detector without batteries. I need the motion detection and the luminosity (lux). Any ideas? ---

Or Xiaomi motion sensors, which last for ages on a single coin cell. Mine have been in constant use for over a year now (used in rooms where people move in and out of all the time) and battery level is still reported to be 100%. ---

Thank’s but any other proposal, I don’t feel very safe having an USB adapter connected on 230V 24/7 (risk for fire)? ---

So no battery and no usb? ---

Yes if it exist… so 230V ---

That 230V will be bucked to 5V or 3.3V internally in the device anyway, so if you use a good brand USB power supply I don’t see the additional risk (also because a PIR sensor won’t use a lot of power). ---

Ok. Any USB good brand proposal? ---

Apple makes good power supplies (although they’re pricey, but I must have 3 or 4 iPhone chargers lying around at my house so perhaps you too), and any other brand-name power supply will be fine too (Samsung, HTC, etc). Well-known “accessory” brands can be trusted too, like Belkin. Always buy from reputable stores so you know you’re buying the real deal and not a fake. ---

The same goes for USB cables… ---

Does the fibaro have interval settings? I have a hue motionsensor. It allows you to change the min update intervals. Lowering the update interval increases the battery life. Lowering the lux update interval to 5 min… Make sure to increase them for all readings (motion, lux, temp, etc) The ones you do not use can be increased even more
