No I can’t say I had any issues like that. Just the initial getting signal outside of the house to the transformer.
You might go outside and verify that each zone on the transformer correlates with the switch/instance that’s shown in HA. The transformer will show which zones are active on the display screen.
Outside of polling it every once in a while, has been pretty trouble free and straight forward for me.
I had a thought on the polling.
Some regular Z-wave devices will send out a broadcast signal when a change is made to the device, which will tell the controller to poll the device, so it will send a status update. But the device needs to be connected directly to the controller and cannot be a hop away. I can’t test whether the transformer does that because of where my Aeotec Z-Stick is located in the house as it requires another powered device to make a hop to the transformer.
