reading inverter.meters() is not working

[Seeelefant]

Dear all,
trying to setup a connection to my inverter and read the meter I get the following results:

>>> inverter.meters()
{}
>>>

Please advice.

Are you sure the modbus ID of your inverter, the unit, is actually 1?

In that direction I have no idea, the only thing I got from my craftsman is that

Is there anything I should do different or tell him to change?

[nmakel]

Try:

inverter = solaredge_modbus.Inverter(host="192.168.0.3", port=1502, unit=2)

Increase the unit value by 1 until you get results.

Well, this looks much better:

Inverter(192.168.0.3:1502, connectionType.TCP: timeout=1, retries=3, unit=0x2)
>>> inverter.read("current")
{'current': 0}
>>> inverter.read_all()

Let me check it when there are some photons working ;-)

Hi! I'm facing the same problem. Got two meters, but no data. Increased the unit until 3 with no luck.
Do you have any other clue?
