Bought two, both connected to a mirrabella Genio without issue, however, the battery clearly states 'Do not recharge', using the cable supplied does not recharge the unit anyway.Was unable to detect motion but it may be due to me using another hub.Product packaging and quality is good and may work if you buy into the Arlec range.

I have spent several hours testing and playing around with various Grid Connect App commands and have come to the following conclusions for my final opinion:With my SG023HA movement sensor, movement is picked up immediately BUT there is a 35 second delay after motion has ceased for ‘No Motion’ to be detected. Initially, I thought this would not be a problem, HOWEVER, if you add ‘delays’ or countdowns in the actions, undesirable things appear to happen if you wish to simply turn a light ON if there’s motion and OFF if there’s no Motion. eg Actions don’t happen when you want or don’t happen at all etc. The only simple way I could see to get around this was to create two automations:One with an Action to switch the light ON, when movement IS detected and . . .One ... MoreI have spent several hours testing and playing around with various Grid Connect App commands and have come to the following conclusions for my final opinion:With my SG023HA movement sensor, movement is picked up immediately BUT there is a 35 second delay after motion has ceased for ‘No Motion’ to be detected.

Fortunately, in my situation, this is just tolerable.I hasten to add, I have had no such problems with the old SGS02HA motion sensors which have proven to be very flexible and very reliable. (However, the battery does have to be replaced now and again.) In my opinion, the new SG023HA sensors should be discontinued in favour of the old SGS02HA sensors.PS: I’ve been running the SG023HA sensor plugged into an old 5V phone charger with the battery removed without any problems. If I have no power, the sensor won’t work BUT neither will the light I wish to control.A quick search on the internet confirms the CR123A batteries used in this sensor are single use, non rechargeable. The current drawn by the sensor is so low, I was unable to read it. Therefore, given the 1600mAh capacity of these batteries, the sensor could possibly run for years on the battery alone; if you wish to run it that way.Accordingly, as I mentioned in my previous review, the micro USB port is NOT a charging port, just an alternate way of powering the sensor.

Can't get it to detect movement at night. Also unable to pair to Grid Connect app without the power Hub, then when power Hub is off doesn't work
