I replaced the shitty BW-SHP13 (_TZ3000_amdymr7l) by SilverCrest HG08673 (_TZ3000_j1v25l17, Lidl SilverCrest Smart Plug EU HG08673-EU Zigbee compatibility).
I’ll probably keep the BW-SHP13 for use as simple on/off plugs and disable power metering related entities in Home Assistant. Not sure if it’s possible to “disable power metering” abilities of the device directly in deCONZ which would be the best option.
Thank you for your input.
