Coprocessor Not Connected - Homey Bridge

A Coprocessor is a second processor in the Bridge (and Homey Pro) that is responsible for some RadioCommunication. Zigbee and Z-Wave have their own Chips.

I have the same problems with both homey bridge Beta’s , at the moment no problems with coprocessor, problems with KAKU began when i trie to make time schedule’s or day and night schedule’s.
All this time modules works over theCLOUD, now i do it old way with ATMT-502 or with Homewizard app

I have the homey bridge, all my web based lights work ok. but when homey uses it’s own kaku and zwave antenna’s then the issues start. (fibaro - klikaanklikuit) :upside_down_face:

I think atom fixed all the problems today , i don’t have any problems anymore.
Fibaro ,zigbee, kaku (rf) is working great.

Yes, functionality seems to have been restored here too.

Interestingly, the Fibaro reaction is some five seconds after all the other devices handle triggering my All-LIghts-Out flow. That’s five lights (RTS, Wiz) within one second after the trigger, and two lights (Fibaro) some five seconds later. But they work again.

I’ll give it a few days to really conclude that the problems have been solved. And I would certainly appreciate to learn what was the actual root cause: the technical aspect of the Bridge and home automation is the reason for having a Homey.

What does your measured latency say?
Here it’s around 50ms atm

Find it here:


29 seconds, but then again, Iive in Athom’s hometown… :slight_smile: (which is no guarantee, I know)

Milliseconds I think😬
Hehe, the servers are in Frankfurt afaik, but you’re closer anyhow then.
I’m on a 100Mbit ADSL so I think a latency around 50ms is pretty realistic :smiley:

Latency: 22 ms (eu-central-1). Middle of Netherlands, 500 Mb/s glasfibre. THIS bit of the Homey Bridge works excellently already for five months, since I have it. But the Fibaro not working, and just now the Coprocessor Not Connected message is not excellent.

I am getting this error message “coprocessor not connected" when using my Homey Bridge with Fibaro devices. All other web based devices work just fine.

When I unplug the Homey Bridge for a minute, afterwards it works again. A few days later, same error returns.

Is there a fix for this?

It’s probably a local wifi issue, the bridge disconnects (coprocessor == bridge)
The bridge needs to connect to an very old style fashioned wifi, like if it’s 2001.

  • Create a separate 2.4GHz SSID
  • In case you use access points: *no hopping! Fix it to one access point (you can use mac filtering / band steering / transmit power tuning)
  • Move the bridge 50 to 100cm away from a wifi antenna ( too close = bad signal)
