I have a simple system with only 8 devices. Two of them are ZEN73 wall switchs. One of them occasionally goes “dead”. The heal function returns “(device name) could not be healed.
Additional information may be available in the logs.” on all switches and a full system heal does not seems to do anything or ever complete. I can’t find anything in the logs about this. The only recovery for the “Dead” switch is to manually toggle it. Then the system seems to see it again.
The problem switch is less than 6 inches away from a Minoston Mini Plug MP21Z which has always worked and claims to also be a repeater. Also the problem switch is in a metal box so I would expect that it would work better next to a repeater. Since the device will not “heal” I assume it is not using the repeater.
Is this a common problem? Could the switch be defective?
What type of controller? There are known firmware issues with 700 Series controllers. Silicon Labs recently released new firmware that appears to resolve some of rhe issues, but not all. See the open Iaaue for details.
Thanks for the info.
It is a 700 series controller. ( never thought of it as a controller, only as a transceiver). It is: ZST10-700
by Silicon Labs Firmware: 7.15
There are 4 battery operated devices in the network so perhaps that is an issue.
As I read other entries, even the current 7.17 version does not fix the issue well. As I have not been able to find the update instructions for a Raspberry PI based system, I will ignore it for a while.
