[XTension] XT and Hubitat (C-8) - units get out of sync

[Brian Williams]

Hi James, 

An example from this evening. My bedroom light switch is a pre-Plus Z-Wave unit. I manually turned it on. A minute later I asked Siri to turn it off. No response. I ask Siri to query the light. Siri reports that it is off - it isn't. I reach for my computer and check the status of the unit in XT. It is marked as being Off. I do a Query from the keyboard. No change occurs. I set the dimmer to 100. A minute later, I tell Siri to turn off the light. The light goes out.

With Siri, if I don't get a desired response, I can command the opposite, then make my desired command again. That usually works. In the above case, if I had told Siri to turn on the light, it would have gone through the motions even though the light is already on (sometimes, a dim command is a better choice since the change can be witnessed), then a Siri command to turn off the light is effective.

I would say that a query from XT to the HE does not actually poll the device, but simply reports what the He has recorded as the status at that time.

I'll think about this more. Possibly an HE reset command for the device is required to synchronize the two. Sometimes I have the HE app 'ZWave Poller' running, but it only polls the non-plus devices, and I don't know the frequency of the polling nor the impact on HE's performance. Poller was not running this evening. I'll test more tomorrow.

Regards,  Brian
