Smart plugs to get power consumption without internet connection

Are there yet any UK wifi-based smart plugs that can report power consumption without need for an internet connection (other than, maybe, for initial setup)? Many people seem to use Tasmoda to flash a Sonoff device such as the S26, but I’d prefer to avoid that. I did see a mention on a Youtube channel that Sonoff devices can now run in local-only mode using factory firmware, but I don’t know if that’s right.

To answer my own question, apparently the answer is yes with this custom component, installed via HACS: GitHub - AlexxIT/SonoffLAN: Control Sonoff Devices with eWeLink (original) firmware over LAN and/or Cloud from Home Assistant. Looks good, and specifically says that it works with the Sonoff S26 in local mode. Will try it.
