AEOTEC Smart switch 6: reports V but no Amp or Wattc

I have 3 Aeotec smart switches I originally used with Domoticz, but migrated to Home Assistant.
After removing and re-adding them (while near the zstick controller), I can see the sensors for consumption (A, kWh, V, W)
The kwH reports a rather large value, i suspect that they rememberrd the old values they had before reset
The V reports goof voltage
the A and W sensors consistently report 0, even though the collected devices (fridges) do consume power

How can I fix this ?

I tried looking in the 'Developer Tools/Statistics) top remove old values, but there are none. hence I think that the 669.076kwh etc re old values still stored in the device

How would one configure low level settings for eaah device?

I a new to HA, as one can see

Yes, the kWh are retained even if you exclude the plug and re-include it. However the reporting of V, A, and W and the associated configuration options are not retained. So you have to set the node up again. If you are using ZwaveJS you go into the node configuration and setup parameters 101, 102, 103 which are the reporting groups and parameters 111, 112, and 113 which are the reporting intervals. You have to enable which values you want in the reporting group. Also parameter 80 may need to be set to “2 - Basic CC Report”. If it is set to “0 - Disable” (Default) or “1 - Hail CC” the reporting function may not work properly. If you want to reset the kWh reading, that can be done either under the “Meter” section of the node in zwaveJS or I believe there is a service you can call from the developer tools in the frontend of HA.
