Third Reality 3RSPE01044BZ incorrect power reported #29573
Description
What happened?
I'm using a Third Reality 3RSPE01044BZ plug to monitor power usage on my dishwasher. Since a few weeks its power usage suddenly increased without explanation. Before, it spiked to about 2000 W a few times during a cycle, for a total of about 0.9 kWh of energy usage per cycle. Now, it consistently spikes to 3200 W for a total of about 1.4 kWh per cycle.
I've finally gotten around to measuring the power with a separate power meter, and the actual usage is indeed still around 2000 W. The reported 3200 W is incorrect. (See pictures)
On the picture you can also see that Z2M is reporting 9.15 A on a 227.2 V circuit, so that should work out to 2079 W, which is very close to the 2087 W that's reported by the power meter.
I've tried with two separate Third Reality plugs, they both show this problem. They're both on the latest firmware. I know it used to be reported correctly, but I'm not sure if the problem started right after updating to the latest firmware. If I can hunt down the penultimate firmware, I'll test with that as well.
