I have a shelly plus 1pm connected to AC socket and updated to latest firmware (0.9.0 beta3). I'm relatively new shelly user and I need some help for the following two points:
1). I have noticed that the voltage reading (as well as the power) is inaccurate. It reads 210-212 V whereas the voltmeter reading is 228-230V. Is there a way to correct/calibrate the voltage for the shelly plus 1pm so that the power can be calculated correctly? Can the voltage reading be corrected by a script (for example)?
2). How can I read the actual power using http request?
