Devices displaying as not in network but sort of work

[garethhowell]

I currently have a pretty simple network comprising an AEOTEC S2, three TKB z-wave power switches, a Danfoss radiator valve and a Horstman thermostat.
As can be seen from the attached images, the network is fairly robust, except for one of the TKB switches and the thermostat. The thermostat is in my office and controls the TKB switch that has an electric heater connected to it.

Everything works, sort of. The issue is device 14 (the Thermostat) and device 22 (the TKB with the attached heater)
According to the graphs and tables, neither is connected to the rest of the network. However, Domoticz can control the TKB directly and does receive updates when the thermostat is changed manually, and does receive the power consumption updates from the TKB

What's missing is the ability to reliably change the setpoint on the Thermostat remotely. Sometimes a change on Domoticz works, sometimes it doesn't.

I see no errors in any of the logs.
