Tompd 63sw Energy monitor values frozen

meh · January 7, 2026, 9:37am

Hey, after installing the energy monitor I noticed that values don’t update, only Total Energy is updating, leakage current voltage current and power have the same value since day 1
flashed the mcu with the latest esphome
I noticed also that my pcb is a little bit different from the device used here TOMZN TOMPD-63-WiFi | ESPHome Devices

Do you see actual updates, i.e. on_datapoint_update debug messages?

I get update only on Total energy and Leakage mA

And what are the values on the display at the time of the datapoint updates?
Maybe that model uses other values…

meh · January 7, 2026, 10:55am

you mean on the device display ? displaying normally refreshing 2-5 times /sec
I noticed that the frozen values are refreshing to Hass each time I make an ota update, probably each time the mcu reboots, to sum it updates all the values after wake up but only keep updating Total energy and Leakage

koying · January 7, 2026, 11:10am

Yes, and I meant the actual values, to correlate with other datapoints, maybe?

Did you try with the tuya app before flashing, to check whether those values were provided to Tuya itself? Maybe that revision of the board only provides meaningful data once, at start?

meh · January 7, 2026, 11:17am

nope, I flashed the device right from the box no tuya app,
yep update at start then only 2 values updates each time, but it’s updating on the display normally

VYuRkAV · February 17, 2026, 5:45pm

Such a problem again — I was lazy and didn’t make a backup, nor did I check it on Tuya. Now I don’t have updates and I’m using incorrect Datapoints.
Does anyone have the possibility to access Tuya and obtain the correct data?

I would also like to add that updates occur only through this datapoint

At the moment I don’t know for sure — one of them definitely indicates a leakage (similar to a residual current device). As for the other one, it’s not clear yet.
