Hi TP-Link Support,


I'm using a P304M to monitor the power of a few desktop PCs. Most of the time the data looks reasonably correct, but every week or so I get a massive spike of energy consumption that is clearly incorrect (over 100 kWH power consumption in an hour on a single socket used by a single desktop tower that does not draw more than 500W) that does not match what is shown in the 24 hour/7 day power graph.

 

For example, just today on 4th October I see a 132.5 kWh spike that is way beyond the norm.

 

Daily Energy Graph for 4th/3rd October as comparison: It is showing a single 132 kWH consumption within a single hour between 2-3AM.

 

Power Graph (24 hour / 7 days). It is clear within 2-3AM of 4th Oct, power draw did not exceed 500W.

 

This affects all the sockets that have other lower power components connected such as monitors/speakers and each of them occasionally spikes way beyond the expected use. Is there any way to correct this error as it makes the data a lot harder to interpret when I have to manually cull some values every few days, and the accurate power graph is not saved after 7 days.

I am also getting the same with my new P304M (Firmware: 1.0.3 Build 240605 Rel.091502).

I have my 3D printer plugged into it, normally uses around 0.1kwh. But the two days I've had it running, at exactly the same time 17:00-18:00, it shows huge spikes of up to 1.465kwh. Before using the P304M, I had my printer plugged into a P110M and never had any spikes like that.

@anTastico The power consumption spike problem here seems to be resolved for me as I have been testing with a beta firmware over the past 3 weeks.

 

You may wish to contact Wayne-TP here and see if you can grab that firmware as well to test if it also fixes the problem for you as well.

Thanks for the info @DaNuker.

 

I'll try and message @Wayne-TP and see if I can get that firmware.

FWIW, seeing this same behavior on my P304M's as well. Was pretty clear there was an issue on the P304M when it was reporting my Nvidia Shield pulling 300W or more!

 

Was about to raise a support ticket when I found this thread!

@Wayne-TP can I get a copy of this beta firmware also?

 

Would be ideal to get this beta and test it before Homeassistant 2024.11 hits stable as support for P304M has just been added (Currently running the beta to get p304m support) Would be good to flag any issues in the Tapo beta firmware and get those fixed in HA also (if there are issues) before TP link push the firmware to public.
