Thanks for all of the replies. I’ve done some additional testing and can confirm that setting Command Poll Period to 0 does stop the polling after sending a command. This helps with the meter channels but leaves the switch channel un-polled. This is probably fine for a workaround, thanks for the suggestion apella12.
I still don’t fully understand when this occurs and when it doesn’t. Are we saying that if you add a net new device and never link a channel for the meter channels, that it will never poll. But if you add a device, link a meter channel, then unlink the channel, that it will continue to poll the unlinked channel?
I intend to test this myself but got caught up in another issue which is slowing me down related to initialization. Zwave device initialization failing after restart - Add-ons / Bindings - openHAB Community . This other issue is causing a problem because I can’t poll a device that’s not yet initialized, so my devices to test on are limited right now.
