9 months ago 3-phase voltage is now calculated correctly ~400V, 1-phase is what ever the device reports ~235V Available now in https://homey.app/en-fi/app/com.go-e.charger/go-e-Charger/test/ test version.

9 months ago Hello Tapio, thanks, unfortunately the voltage remains 400V when charging in single phase. I’ve used your link below, I saw in the change log, you’ve updated the Go-e app twice recently, 2.7.0 and 2.7.1, both on voltage calculation. I’ve installed the latest. I will try later again, when my car will start charging again, perhaps by then your fix will visible?
Cheers,
Norbert

9 months ago The existing measurement for voltage is the one for the source. There is new measurement Output Voltage for what is delivered to the car.

9 months ago Hello Tapio,
Thanks, indeed, I think I overlooked it this morning or it got fixed after the first charge this afternoon. I also disconnected the charger from the grid-power and rebooted it. I rebooted Homey as well and so the go-e charger too. This is the result when I switch between one and three phases charging, see below. That is perfect, thanks!
Cheers,
Norbert

Thanks for the fix again, appreciated! I’ve got another one, not about the electric current, but voltage. For single phase charging sessions, the go-e charger homey app adds up all available voltages provided by the Go-E charger. That would be something like 700 to 710V, which is odd. See the screenshot of the Go-e charger app in Homey. Voltage in single phase should be in the range of about 225-240V. I think this can be solved by retrieving the phase (L1,L2 or L3) where there is (or was in previous charging sessin) a electric current present.
For charging at three phases, 700-710V is not corrent either. It is a bit more complicated to get it right, it should typically be in the range of about 380-410V. A suggestion how to fix it: You can roughly calculate the correct voltage by mutliplying an active single phase by the square root of 3 (approximately 1,73). As an example:
234V * 1,73 = 405V (L1-phase)
When there are three phase active, you can take roughly calculate the mean of the three voltages and multiply it by 1,73. As an example the voltages in the screenshot of the original android Go-E charger app:
((234V+239+239)/3 ) * 1,73 = 410,6V.
Can the voltages in your go-e charger homey app be fixed for sinlge and three phases charging?
Thanks,
Norbert
