Did you do a secure include on the node? Also what is parameter 80 set to? If that is set to “Hail” your network will have a hard time talking to it because it’s flooding the network with updates. There is a command/way to reset the energy meters, it’s not through a parameter, rather a Zwave service command. I’ll have to dig through my notes from a few years ago on these.
You can always do the factory reset procedure after excluding the switch from the network. Hold the switch button for 20+ seconds and it’ll go through a color/light show and reset to defaults.
