I have four of these plugs and they have been working great. I noticed this morning that I wasn't getting any readings on the consumption and I see that all of them are set to Null.
I have tried to re-interviewing via Z@M but that did not work. So I then removed them from Z2M and re-added them back and still the values report back as Null. I did flash to the latest firmware version, V1.00.88 when i first added them to Z2M, weeks ago, and they never gave me any issues. Has or is anyone faced this problem? Any recommendations on troubleshooting the devices so it outputs the consumed energy values?
