i have been using the originals for some time on low power usb and they work great. I recently got some usb points installed around the place to make it a bit neater but have just reeliased the amps on these usb points are 2.7. the motion sensor only needs 550ma.
I have found that using the sensors on these new points causes them to stop responding after a few days but they come good straight away as soon as you unplug the usb.
any ideas on how i can reduce the amps on the usb point? i’m guessing just plug something else in that uses power…
might need to take these out and re do them
or if there is a newer model zigbee repeater that powers by usb out there that works with smartthings that could work (I can’t use zwave)
You don’t have to reduce the AMPs. It will just draw less current than it needs to run. The amps is your max rating, not your supplied rating. Thing of the wiring in your house…you have a 20 amp circuit breaker but you don’t have 20 amps running on each circuit, right? Same with this. You have to have enough amps to power your device but having too many shouldn’t be a problem in this case.
Also try another DTH as well. ST changed the way its reading battery % awhile away due to all the complaints about inaccurate reading and since then any out of range voltage will either freeze the sensor or crash the app. I find mostly over voltage is the problem.
Edit: I only have one of this sensor but tried many USB adapter without issue. Maybe wifi interference or mesh as well.
