Plug-in Switch Mini - TZWP-102 - Wrong power reporting? #45

Open larsi70 opened 1 year ago

larsi70 commented 1 year ago

I have three Telldus Plug-in Switch Mini, all of them are reporting incorrect power/wattage usage. I've tested a few different loads to better understand, and it almost appears to be reporting % usage rather than W..? a ~1000w toaster is reported as ~50w, a ~1000w toaster AND a ~1000w kettle is reported as ~100w while a ~30w lamp is reported as ~1,5w.. I have excluded and included the units multiple times without it making a difference.

Hi, this is strange. I just tested mine with a Kitchen Aid blender and it seemed to report correct as far as I can understand. It reported between 0-300W and only 300W when it had a lot of resistance.

There is no possible way to change the readings from W to % or the other way around as far as I know, and as I said, it is working for me... Did you try changing the setting for Wattage report threshold? And is the insight graph also displaying consistently wrong values?

Hi, your graph looks more correct.. I can only assume I have a different firmware on my devices or something like that. I tried some heavy Googling before reporting the issue, but I couldn't find anything useful. I have tried connecting multiple devices, even loading it towards max, and the highest reading I have seen was around 100, when drawing close to 2kW.

Below is a full dryer cycle, with an average of 30w, which makes no sense, the real wattage is probably closer to 600w..

I think I have tried both with fully default settings and playing around with whatever settings are available without any notable changes to the reporting.
