Accuracy of Shelly EM devices (Messgenauigkeit von Shelly EM)

Hi. I'm planning to but a Shelly EM for household consumption. Sadly there's no info on the device's accuracy anywhere. Does anyone have experience with it, or any figures for accuracy? I'll probably get 2x50A CT clamps with it. Thanks in advance.

Thanks, SparkyMaster. Is it noted somewhere in the official docs? Maybe it just escaped my attention. 1% sounds good enough - I guess no figures on calibration data, like phase shift vs. current and accuracy at different amperages?

Sorry, it could be my mistake, but I haven't been able to find the 1% figure in any of the official pages, nor in your lexicon link.

The available technical info is on the shop page, table screenshot attached. No accuracy there, either.

FWIW, I received the following "specification" for the accuracy of the device:

"The accuracy at the moment is about 98 %

The clamps are calibrated, you cannot use another ones."

Please do tell if you can figure out the actual accuracy of the device after reading this.
