I'm trying to bind a KE110 sensor to a KE100 Valve using the H100 hub and Tapo App. I get a "Network unstable" message or simply "Failed", even when all three are 4 inches apart!

Both devices are connected to the same Hub (if I go in to the Hub Connected devices, they both appear as Thermostats)

I have several KE100 Valves that all work fine.

I have several KE100 valves bound to T310 or T315 sensors that work fine.

If I try to connect a KE100 valve to a Tapo Sensor it works fine

If I try to connect it to the KE100 to the KE110 I cannot even see the KE110 in the list to connect to

The KE 110 connects to the Tapo App Fine

If I try to add the valve through the KE100 connected devices button on A KE110 I get a "Network Unstable" Error

If I reset both devices and try to bind them at the end of their process they fail

Am I fresh out of luck trying to get the KE100 nad KE110 to work together using the Tapo Hub and App or should this work?
