(Posting in hardware since I don’t yet know if it’s a HASS z-wave issue or a device issue.)
I have several Aeon Labs (Aeotec) Gen 6 smart switches. Occasionally, any one of them can report an insane power draw, as shown below. The spikes can be reported whether or not the attached equipment is actually drawing any power. I know because I made some automations that check for power consumption changes, and I had to set a time threshold to prevent the spikes from triggering them.
Does anyone happen to know if this is a known issue with this hardware, or perhaps it’s an issue with openzwave?
I have 3 of them and I’ve seen one reporting very small power draw (0.05A) but nothing like you and not from the other 2. It might be a bug somewhere in the firmware but it’s related to the unit you have.
I’ve noticed this too with mine, both the smart switches and the nano switches. They all report ridiculously high power usage numbers about once a day which is excruciatingly annoying. I don’t use home assistant either, so it’s not my HA set up. Did you ever figure out a solution?
I haven’t played around with it though, but I guess the Range-filter and setting an upper_bound limit and replacing every “spike” with just some normal value should work.
