Since update of HP2016 (Early) to 10.0.5-rc2 I get this message when I try to turn of lamps (all at once or one by one). If I restart Homey the message will not occur. Anybody with a hint?
I think you should report this to Athom, while you run beta firmware (you’re a firmware tester now).
You can revert to stable firmware I you don’t want to be a tester:
Many thanks Peter_Kawa. I have restored my old white ball and now int seemes to work! I repoted the issue to Athom but there is three weeks waiting time…
Again thanks for your advice and Happy New Year 2024!

No problem, Peter, nice to hear.
They say “expected response time: three weeks”, which is not the same as “it takes us three weeks” 
It probably is stated to prevent users from requesting ticket updates every day.
Which slows the process down even more 
There’s a priority system, some users got helped the same day.
I thought that my old HP2016 was ready for the bin. So I ordered a HP2023 and got it the day before yesterday. GREAT!, I thought: easy to migrate from the old one with the back-up, a little extra time spent on Zigbee devices that needed to be reinstalled. But I think Athom already thought of this and had made the procedure fairly easy to do.
WELL… Last night when I wanted to turn off all lights in my living room: RED ALERT! “Reached maximum message queue size” Same story - restart Homey and all of a sudden it works.
O’boy, was I disapointed! Now I am in waiting mode for Athom’s reply on my ticket - for the old HP2016
To be continued.

Having the same issue. Leviton zwave device is giving the same error. Works for a day when I restart it. I’m considering giving up and returning my homey device. This is supposed to make it work with Alexa but not a thing has worked so far. I tried some smartwings zigbee window shades they don’t work. Give an error message during pairing.
I solved my problem by using the app
