We have our water heater set up on a timer, it’s a zwave model. On at 5am and 5pm every day. Time of run is dependent on outside temperature - typically 30-45min.
When it’s on, it’s pulling 5k watts almost the whole time, but only about half the time is the whole curve recognized.
Based on some more anecdotal data, I’m almost sure it’s having the most trouble when other devices are running - especially the heat pump. Yesterday morning, the heat pump was running and accurately identified… Up until the water heater came on. The water heater was recognized for a hot second, then both dropped to “unknown.”
I’m commonly seeing problems with fridge shutoff recognition, complicated by heat pump activity. We were gone for a few days (heat pump turned down), and the fridge recognition was near-perfect. Heat pump on - fridge shutoff detection goes down.
I should note - I do not have the halving problem with the heat pump, it gets both phases. However, it correctly detects it just 80-90% of the time.
Wonder how common all of this is?
Here’s the messy fridge:
