Is it possible to read two meters using same service ? or using same converter?

or need to add two services?

As the name says Modbus is a communication-bus. On a bus may a bunch of clients be connected to one converter, each with a different address. You tell gosdm the devices on the bus with paramter -d. For example -d SDM:22,SDM:23 two Eastron SDM-meters, one with adress 22, one with 23.

You can connect multiple meters but they must have different modbus ids.

Thanks!! working great

what speed is recommended?

andig commented 5 years ago

The exact speed that your meter requires!

Well, you have to take care alle meters on one bus are on the same baud- and framerate. I suggest al least 9600bd. The SDM120 are delivered with 2400bd, thats pretty slow.
