Wrong Data - maybe an issue with Shelly 3EM Code

[fellpower]

Hey

i have a balcony pv with 2 x 410W modules and a Hoymiles HM-800 as PV Inverter. works great, opendtu works like a charm.

• I have no multigrid II
• Hoymiles HM800 at L3 conncted
• Raspi4 as CerboGX with Venus OS
• Shelly 3 EM installed in the Mainline, in FRONT af the whole house - and installed the code in VenusOS for it

Now in my oppinion something is mathematical wrong. See the picture

i get 40W from my Hoymiles Inverter - that shows as -40W, thats correct, because the shelly is measuring negative, if im bring in power, that i dont use.

i confd the opendtu code as pvinverter. because its doing this. it on L3 and inverting fine.

[INVERTER0] Phase=L3 DeviceInstance=34 AcPosition=1 Servicename=com.victronenergy.pvinverter

Shelly is confed like that:

[DEFAULT] AccessType = OnPremise SignOfLifeLog = 1 CustomName = Shelly 3EM DeviceInstance = 40 Role = grid Position = 0 LogLevel=ERROR

[ONPREMISE] Host=192.168.0.69 Username= Password= L1Position = 1

if im put opendtu in at ac pos 0 - it wont show up (plz why?), if i put it as ac out 1 - it works, but for the cerbo its a load, so it puts that -40W to +40W at the load end.

the shelly is confed on grid40

So something is wrong here - maybe with the shelly code, or yours, i dont know. or im wrong :P

it works fine and well with a real existing multiplus, also rather check the values you see under the individual devices in Venus Console.
