4 way GIRIER Switch sends status but doesn't receive

[olleman]

Hello!

I installed a GIRIER 4 way switch in my garage a couple of days ago. It's been working on and off ever since but since 2 days it's never taking commands from Domoticz and Zigbee4Domoticz reports it as "UNREACHABLE" for a short period of time. If I however switch it with the physical switch attached to it the status is instantly reported in Domoticz.

This router is a far away and does not have a direct contact with the coordinator but rather with 3-4 other routers and the LQI is about 100.

I have attached the plugin log. The switch is called "Garage"

According to the comments regarding a GIRIER dimmer switch they have reported a similliar problem.

I created a group for one of the switches and it does indeed work when I try to switch the group instead of the switch itself. Please note that switching the switch itself sometimes work so the problem comes and goes.

It seems that the problem is relateted to the GIRIER switch having trouble receiving the signal. When I increaded the signal strength in the advanced settings of the plugin to 15 it's been working flawlessly without groups. Is it possible that the MESH network only works "one way" with this switch? The topology scan shows that it has several good connections to other routers and the status signal has always been working since day one.
