Hi,
im struggling to understand how to setup the grid connection in the new energy dashboard.
Do i set a "grid" for each phase or just the total? (i have a shelly pro 3EM)
For the energy imported from the grid, shall we use an integral counter that only counts positive power?

Exactly what you set up will depend on where the Shelly is wired in and just what it's sensors look like. I can't remember if it splits out an in/out energy sensor natively.
If it doesn't, then yes, the best then is to make 2 template sensors based on the power meter. One does max([states(sensor.shelly_power) | float(0),0])to give you the net positive power, and the other does -min([states(sensor.shelly_power) | float(0),0]) to give you the net negative power. Then integrate each to get energy
Regarding the phases, again, it depends on what the Shelly offers, but either a total in, or adding the 3 phases separately will work

My shelly is right at the grid entrance.
Shelly offers both options: total and per phase.
