Hi
Any updates?
I see other apps like Namron making often updating the version.
Any plan?
My Develco sticks leaving the network after a few hrs.
As i can see, the problem start when more than one Develco plug is in operation.
We’re investigating the issues reported, together with Develco Products engineering and Athom development. So far we have not been able to reproduce these issues on (extended) setups at all three locations, nor are the diagnostics reports of either the app or Homey conclusive.
Several Homey’s running here with a mixed setup (multiple plugs and sensors) without devices leaving the network. Do note that all Homey’s are either new based on v5+ or have a reset Zigbee network after updating to Homey v5.
I’ve reached out to a local home automation shop who is reselling the same devices to inform me when
they have customers experiencing similar issues; to be able to capture the Zigbee communication with a Zigbee sniffer.
Additional information about your Zigbee network would be helpful to resolve this issue:
- Provide a Zigbee health report
- Provide a screenshot of the overview of the Zigbee network: as shown on Homey Developer Tools
In parallel, I am extending Homey’s Zigbee implementation to provide a few additional responses by Homey on the devices requests.
At this moment, resolving the disappearing devices has the highest priority.
Then we’ll add support for additional devices.

I assumed you might wanted it here?
I’ve sent diagnostics of Zigbee network to the thread in link provided, or wanted you this here as well?
Extra info: I just realized that two devices left again…should have been 2 more smoke detectors here
Extra info 2: Before I ended up with only Develco Zigbee products in Homey Zigbee, I also had IKEA without HUB in the same network. But it was unstable as well, so I added them back to the original IKEA Trådfri HUB, so now it seems stable for IKEA. But then again, there are no “power” devices left on the Homey Zigbee network to act as “repeaters” that also might be an issue with connectivity, but I would NOT expect them to leave network, but throw a “cannot connect” staus instead of leaving

Hi, I’ve added my Develco leak sensor again to retrieve a report when it leaves the network. The pairing was a little weird. When I followed the instructions, the device would not pair. Then I disconnected the battery and connected it again the device started to pair. After a few minutes, Homey sends a message that the batteries were OK again. (The battery shows 100% both before and after).
Just picked up 4 Develco Motion Sensor Minis and am wondering if anyone knows how often they run a check for lux/movement? It doesn’t seem to be as often as I’d like because sometimes they don’t respond even when I’m waving my hand directly in front of one. Is there any way to shorten this interval?
Bought two motion sensor minis last month. First one left the network, then yesterday the other.
Not sure how long it will last when I readd them…
Any updates on zigbee units leaving the network.
No progress after update to ver 6.1 either

Same with me. if possible even worse than before. units now leaving the network the same day.

Hi. Is it possible to disable the blinking lights when the motion sensor mini detects movement? My kids think its kind of creepy with a green blinking eye in the dark 
I read the manual and know theres an option to disable it, but i cant find a way in homey to adjust settings. @TedTolboom
13 days for the kitchen sensor to be readded, then now today, left the network again
Added it again, and now it left after 6 hours
Checked everywhere?
Hi again. I would like to let you know that after I added a Repeater/router to my Zigbee network it now works. I dont know why, but the develco products are in short range to my Homey, but connects via the router/repeater instead and works. been working for 10 days now.
do you have repeaters? or only the homey that spreads the network?
I have an ikea repeater, but it goes directly. It’s very close to the homey.
A brief update on the disappearing devices, after contact with Athom and Develco Products development.
In summary, the issue is appearing to originate in networks where the Develco Products devices are in the same Homey Zigbee network with ‘older’ Zigbee devices (e.g. older Ikea bulbs). The event is triggered by a communication of a Develco Products device to Homey appears to be not fully processed by Homey resulting in the device has left the network message.
To resolve this issue, Athom has added additional diagnostics within Homey v7, as released as Release Candidate towards the Experimental channel yesterday.
If someone experiencing this issue has already (or is willing to) updated towards Homey v7, could you send me and Athom support (support@athom.com) a Homey diagnostics report (code) (App > Settings > General > Send Diagnostics Report) after you received the device has left notification?

ok!
After extensive debugging together with the development teams at Develco Products and Athom, we have identified the issue of the disappearing devices.
The Develco Products devices can send a leave notification with rejoin option when the connection to it’s router is lost; specifically when the mesh is using older Zigbee devices (e.g. a first generation, not updated Ikea bulb). This is a normal Zigbee routine that should re-establish a new route through the mesh towards the controller. Previously, Homey did not take the ‘rejoin’ option into account, and therefore removed the Develco Products device upon request.
With Homey v7.0.0, currently in experimental release but anticipated to be released to Stable soon, this issue should be fixed:
Changelog Homey v7.0.0-rc.14:
- Zigbee devices that leave with rejoin will no longer be removed
No update of the Develco Products app is required.
Over the last days, I’ve done several experiments with both sensors and a wall plug, connected through an old Ikea Tradfri bulb that was disconnected over time. In all experiments on Homey v7.0.0 the devices reconnect successfully after some time. Based on these experiments, I am confident that the issues experienced will be resolved.

Looking forward to hear your experience with Homey v7.0.0.
Did it resolve the leaving devices for you as well?
For me haven’t had any issues as of yet. So very happy with the update if it continues 
Thanks for your work here
