Tuya-Convert might not be possible for this device since the template was added (2020-06-08). All new Tuya devices have firmware preventing flash but it is still possible to Tuya-Convert old stock devices without connecting them to the Tuya app.
You need Tasmota 220.127.116.11+ to support the new power metering chip.
This template is only for SHP10 WITH POWER METERING. Non-power metering version looks identical and is sold under same model number. Check the barcode on the box: POA6204581 is the non-power monitoring version, while POA6204582 is the power monitoring version.
