I don’t think it’s the antenna or the signal. I think the discovery and/or retention process is not as reliable as it should be. I hope they are able to fix it.
I have 2 sets of sensors so 4 door, 2 motion and 2 bridges. One set is fine but the other set has been offline for a few weeks now and I just noticed. I too rebooted the camera and while the sensors come back they immediately go
Offline again. Seems like there are a lot of the exact same issue yet no response on what the fix is. Looking forward to answers here before I think about expanding my system. Reliability is a big deal with these type of products.
Only had my system for 2 days and now the motion sensor and the contact sensor have gone off-line. I have rebooted the camera but no change. Any suggestions or have I done my dollars?
are they far from the bridge? If you could bring it closer to the bridge, does it go online again? If it’s a range issue, one thing to consider is to antenna extension trick discussed in another thread. Otherwise, best thing to do is to contact support. They are slow to respond but they do respond and should be able to help you.
my motion sensor is offline no matter what i tried,
singal strength is still good and i removed from app and reinstalled, same thing
I’ve had mine for over a week now, I’ve removed and readded the hub cam. I’ve reset the hub. I’ve removed and readded the sensors. I’ve added an antenna to the sensors (this is impossible to do on the motion detector). The sticky pads are shot from trying to reposition them to make them work, so I had to add my own double sided tape. The “about” from the last time that the sensors were online show multiple bars, but they will never come back online after the initial install. One sensor is sitting on my kitchen counter about 25 feet from the hub in a bedroom - and it is offline. If I could return these I would, but since I modified the sensors to add antennas and had to replace the stick on pads so this is no longer even an option. I am EXTREMELY disappointed with this product. What a waste of money.
I could fix my problem just relocating my gateways to a different place inside my home. I think problem is related to wireless signal interference. I think the wireless antennas or devices inside this sensors are not powerful enough to keep a strong signal or communicate with the gateways. after moving my gateways to a different location my signal improve and sensors are working ok for about 5 days in a row.
SInce the hubs have to be attached to a camera, then this would mean that one can’t put the camera where it is needed…so this is not a solution. I currently have one sensor sitting on my kitchen countertop less than 20 feet from the hub, and the sensor has been offline since I originally added it last week even though I’ve reset the hub multiple times. I’ve even added a six inch antenna to one of the sensors that is also about 20 feet from the hub in another direction, and it has 3 bars as signal strength from when I installed it, but it is offline as well.
Based on other reports the hub can be linked to the camera with a USB extension.
I unplugged the hub from the camera, re-inserted it and now all is working so maybe the hub was not inserted far enough.
The motion sensor worked once but now it still reports Motion detection in progress even tho its been put away in a box for a day. It will still detect motion, just never shows as going back to the clear state.
I"ve already removed the hub and plugged it back in. No change. I also don’t want to use a USB extension for two reason…1: It is already difficult to hide the current wires and 2. the hub would still be in the same room so not sure how this would help.
I used to have one bridge with 3 sensor and never had this issue. Recently I bought and installed another bridge with 5 additional sensors. Now just 2/8 sensors are working, rest are offline. Even the ones that used to work don’t anymore…
I have three sets of the sensor packs. One in operation in my primary residence has never had a problem since the early adopter period and continues to operate flawlessly. The second and third sets I ordered later. The second set is installed in our second home 1000 miles away about 30 days ago… That set of sensors, unfortunately, is the one that just went offline. The camera where the bridge is attached is still working fine (for well over a year). I suspect the bridge since all the sensors seem to have gone offline as far as I can tell at the same time. I anxiously await when Wyze identifies this problem since it clearly is happening to some significant percentage of the devices in operation.
Not sure if this applies to anyone else, but my 2 Motion Sensors and 1 Door Contact will go offline 100% of the time the moment I talk into the microphone (two-way talk) of the camera with the bridge. I’ve done this now probably 50 times … and the sensors go offline every single time.
Like everyone else, the sensors will go offline randomly about once a day. A simple reboot of the camera fixes that … but I have to check the system frequently to make sure they are not offline.
Just curious @Gboy, have you provided that as feedback to Wyze yet? I’m sure they would be very interested to know about this bug. If not, please submit an App Log and/or a Firmware Log.
I have not, I just assumed this was a known bug and was applying to others as well. That’s why I was asking if others have had this issue.
I asked because I haven’t hear of this issue before, and it’s one of my jobs to lookout for possible new bugs. 
I still have not been able to get my sensors or motion detector to work where I need them. I’ve done some experiments to figure out why. Both sensors are approximately the same distance from the hub inside my home (about 20-25 ft.) One is on my metal mailbox at the front door, and one is on my metal garage door. I have tried the sensor AND motion detector on the mail box (inside) and neither worked. I took my extra sensor and used the phone app to see how far the sensors can be from the hub and when they quit working. Both work fine until they touch the metal. The mailbox sensor will work up to about and inch away, then quits when I actually touch it to the metal mail box. The garage door sensor works until it is about six inches from the metal garage door, then stops once I get any closer. So I’ve come to the conclusion that these sensor cannot work on a metal object, but I have seen other posts where users have been able to get them to work on metal…so I’m perplexed as to what to do now.
Same issue here, there is no point of having them if they keep going offline, Wyze are not answering my emails.
I will just dispute the charges and get over with.
I removed my motion detector from inside my metal mail box since it never worked, and now I cannot even reconnect it to the app, so it is now useless, and the sensors will not work when the come in contact with metal (such as a mailbox or garage door).
