Vera: errors after adding (too many?) devices

Configuration
1

For a while I’ve been using home assistant together with my Vera edge z-wave controller and the vera component. It work like a treat, but now that I added a lot of devices last weekend (light switches and motion sensors), triggers from the vera are often not picked up.

In the hass log files, I see a lot of errors like these:

It seems like the vera thinks hass is polling it too often and is refusing connections. Is there anything I could do about this?

It certainly does look like thats the case. I’m not sure right off hand what could be done but I can look at the code and see what could be done. How many devices did you have before, and how many do you have now?

I actually think there’s something wrong with my Vera unit, after removing several devices (more than I added before the problem) I still get a lot of these errors. I’m now in the process of moving to a aeon labs stick instead of the vera which seems to be a better solution after all.
