Jasco 14285 40-Amp Outdoor Switch and power metering

Those logs have me wondering if the device is responding to the polling. I was expecting to see something indicating a response in the log - the DTH as posted on the ST GitHub has some log statements that I think should print for each incoming z-wave command.

Correct, you would switch the device type to Z-Wave Tweaker, change the parameter, then switch back. No excluding. There’s an updated version of Tweaker in the post below that should work with the new app.

Polling a single device like that shouldn’t mess up your mesh, so long as you’re only polling the attribute you care about and not doing a full refresh.
