Energy meter in Node Red not accessible

Hi,

I have a system with two energy meters (configured as AC Load) and a grid meter. In Node Red I cannot access the energy meter and the node indicates:

"There are no energy meter services available. Please check that a energy meter is connected or try a different node. "

All energy meters are of type ET340.

How can I get reading of the two energy meters into Node Red?


Thanks,

E.

You will have to see if there is a pallet available for them. They are not a victron product. It will be like if you are using the sonof kit or other integration. I think... I have not tried it

Hi @nam-erik,

how did you solve it? I also have two ET112 energy meters defined as "Grid" and "AC Loads" each one with his USB/RS485 converter.I can see both in the Energy meter list with his serial number but only one of them as a Victron Device "AC Loads". So therefore in Nodered I get exactly the same error message when I want to use the Grid node. You have any advice how to use both of them with all functions?

@usernamepasswordbs One meter should list in the AC Load node the other one should list in the Grid Meter node. Another thing you could do is download the Carlo Gavazzi software UCS Desktop configuration software and change one ET112’s modbus address to 02 then you can parallel the two meters on the same rs485 to usb cable. I can’t say if your two meters might be conflicting in node red even with two separate usb to rs485 converters as mine are setup as 01 and 02 on the same usb to rs485 cable and never had a problem.

In those nodes I have "no AC load* services available" so not able to use them for anything.

However, thanks to someone here, I have found AC consumption in the Victron "System" node which does the job.


*or Grid meter

I know this is an old topic, but.,. For the ET340 in Node-Red we have Grid-L1 till L3.
Is it possible to have both kWh counters as well? (Consumed and delivered). (Not the separate once... Or as bonus)

Look at custom nodes. If it exists in dbus, you can use it.
