How to calibrate sonoff SPM?

[quinti123]

hi there,
I have a sonoff SPM. When i attach a 60W bulb (really consuming 60W, testet with power meter), the metering of the SPM says 75W
Is there a chance that the calibrate function will be activated in future versions?
May somebody has a build with this function acivated?
thanx in advance!

For Tasmota there is no way to calibrate the SPM. All energy monitoring is done in the Relay modules with dedicated firmware.

From the Tasmota sourcecode:

Each SPM-4Relay has 4 bistable relays with their own CSE7761 energy monitoring device handled by an ARM processor.

Sorry.
