I’ve recently added a couple of Innr SP242 plugs to my zigbee network (ZHA) and observing the values output from the plug all looks sensible apart from the SummationDelivered, this appears to b out by a factor of 100 - apparently my washing machine has consumed 250kWh today!
I can see there were some similar issues on github with other innr plugs but looks like they were resolved some time ago.
Can anyone advise how to get sensible readings out of my plug?
I found your question when I was having the same issue, but managed to fix it.
If you haven’t yet fixed it, or if anyone else comes here looking for the fix, you need to install a ZHA quirk, which was originally for the SP240 but works for the 242.
Full procedure:
Install this quirk but change the references to the SP240 to SP242
Remove device from HA
Reboot HA
Put the SP242 into factory reset (long press side button until LED flashes rapid green)
