Is anyone else in the UK experiencing loss of motion Sensors this morning?
Hub log is showing two updates this morning and no further events after.

thanks

Happened to me yesterday. (US though)
Have you tried remove the batteries from the devices, wait 30 seconds and put it back? Worked for me and hope it will work for you too.

Mine are working fine this morning. Triggered motion when I got up.

This may or may not be relevant, but just in case:

Zigbee devices (bulbs, sensors, switches, outlets) randomly failing beginning March 2016

I am seeing a number of reports in many different threads since the March meltdown and the subsequent implementation of the new scheduler indicating random problems with a number of different zigbee devices, including smart bulbs, motion sensors, pocket sockets, etc. Most people are reporting this as a failure of the device, but I’m not sure it is. It may be a failure of the cloud to properly record the events, or database corruption, or local flooding. It may be devices using a device handler that has the known millisecond problem. The new scheduler which was rolled out in March has a missing converter and treats milliseconds as seconds, so device handlers with programmed delays will wait 1,000 times longer than they should. This might cause a timeout, or what appears to be a failure t…

Thanks for your detailed reply, much appreciated. I did pop the batteries on the sensors, some worked again some didn’t. Really hard for me to correctly diagnose as I’ve just installed a new router and lost hue, alexa and harmony at the same time so it’s been a massive reset but smart things really is the only thing that isn’t functioning properly. I can definitely agree that it’s generally become much slower since March.
