Recently migrated from ST with 15 of my GE z-wave switches that don't report state changes automatically.
My automation that relies on knowing the state of switches (e.g. "if light stays on for more than 1h, turn off") is no longer working as a result. I understand that replacing these with z-wave+ would fix it, but this is not an option for me given the monetary cost.
I'm therefore trying to get the "Z-Wave Poller" app to alleviate this. Unfortunately it is not working. Symptoms:
a dashboard with tiles of the offending Z-wave switches and dimmers correctly updates when changing the state of devices digitally, such as via a voice command through Alexa
the same tiles don't update when physically changing the devices state (by pressing on the switch).
Verified that the devices are listed in the poller app's settings and that polling is started. Enabled logging but not seeing any relevant logs under Logs or System Events.
Sorry my first bullet after symptoms wasn't clear enough. Yes, initiating device state changes digitally works both from the device's perspective and from the dashboard perspective. That includes Alexa and the dashboard. It's only when the changes are initiated physically that the device state is not properly updated.
Nobody likes to hear this suggestion... Replace those old switches with modern ones.
I ripped out all of my frustrating GE Z-Wave (non-plus) switches and went with an entire Lutron Caseta lighting system. I don't miss the problems of Z-Wave at all. I am sure new Z-Wave Plus devices are much better, however I decided to go with the 'sure thing' in Lutron. I have never been happier with a home automation decision. Caseta directly integrates with Amazon Alexa, Google Home, Apple HomeKit, Logitech Harmony Hub, Hubitat, SmartThings, Home Assistant, Node-RED, etc... It just works - every time.
You mention that you have 15 of these devices? What other Zwave line powered devices do you have? Maybe some newer repeaters or repeating devices might help somewhat, especially with the failed issue above.
