EcolinkPET Immune Motion Detector Zigbee PET Immune Motion Detector, White (PIRZB1-ECO)

Unfortunately with the very many disruptions in the Wink service that uses zwave, I gave up and I ended up replacing everything with zigbee devices using Amazon Echo2 as hub.The existing Ecolink zwave units were great. The Ecolink zigbee disappointing so far. Not getting the detection area as before and the way of setting the sensitivity using a magnet is odd. If Echo ever supports the zwave protocol in the future I will reinstall those devices as they were less intrusive and easy to mount.

Motion detection functionality is good. It's new, so I don't have an estimate on battery life yet.The case separates on the back to maintain the battery. This is a pain as the case is VERY tight and just about impossible to slide apart by hand. Since there is no external mounting bracket, this will make changing the batteries every x months a real chore. Took off a star for that design decision.

pairs ok with Echo, but doesn't report movement (even when im directly in front of it) - which is odd. Ecolink makes a perfectly fine z-wave version of this, but the zigbee version is not fully cooked, or maybe mine is faulty. The options for mounting this is also pretty inferior to the z-wave version.... the way this mounts means you will be unsticking it from the wall to change batteries, so you will likely need new tape and possibly damage the finish of your wall. Ive moved onto another brand that is more reliable and mounts with no hassle.Regarding connecting to the echo hub - Ive found that Alexa will report that nothing is found, but if you go into the app you will see it there.

It works for about an hour or two then it just stop detecting motion. Only way to get it back up and running is to remove both batteries and re install them. Then motion detection feature works for couple hours. Temp sensor continues to work though. must be a bug. can you firmware upgrade these?

After initial test phase of installation is done it doesn’t detect motion.

I'm not sure if it's something I'm missing, but it doesn't seem to work correctly. I have some other motion sensors, and tons of smart home devices, so I'm not new to this. The motion sensor paired just fine with the Zigbee hub in my Echo Plus and initially senses motion and triggers an Alexa routine to turn on some lights just fine. However, once it does that, it seems to stop sensing and triggering the routine. I read the instructions and also checked on the manufacturers website and from what I read, it's supposed to reset and rearm 2 minutes after a motion event. It doesn't seem to do that in my case. I also tried deleting the sensor from the Echo Plus and pairing it to a Tuya Zigbee hub and it paired just fine there also, but I had the same problem where after the first couple triggers it seems to stop. I wait 5 minutes, watch the sensor in the app which shows clear and as I walk into the room, it just stays clear. I really wanted to use this to replace a cheaper sensor that eats batteries too quickly, but I don't think this one will do it.
