Setting battery capacity issue

[campervantime]

Hi

I am using your BatteryAggregator to give me a single battery monitor view from 2x smartshunts that I have. One is installed on a 70ah AGM and the other on a 92ah AGM and both are working correctly.

I installed BatteryAggregator and did not create a config.json, and everything appeared to be working apart from Aggregator didn't know what battery capacity I had installed, it just appears as 0 when I look in the setup menu for Aggregator. Time remaining, SOC, current etc all seem to be operating though.

I then tried to create a config.json (see below) but I got errors (see below) and the battery capacity still wasn't set.

Is setting the capacity really needed in my application or is it only useful where there is no source for time remaining from the BMSs/Shunts?

Thanks

Config.json......... { "capacity": 162 "primaryServices": {"com.victronenergy.battery.ttyS5": ["/Soc"]} }

That's a bug, fix pushed. BTW, dont know if it is a copy+paste error, but you are missing a comma in your config after the capacity line: { "capacity": 162 , "primaryServices": {"com.victronenergy.battery.ttyS5": ["/Soc"]} }

Thank you - I'll give it another try. Is the capacity figure used in my scenario for any purpose?

Have also just tried but no joy -

that's with using the following config.json:

{ "capacity": 162 , "primaryServices": {"com.victronenergy.battery.ttyS5": ["/Soc"]} }

Pushed fix for that.

Thank you :)

When I try to update on the Cerbo via Package Manager it is still only showing .49 - I presume there should be a .50 now?

[pulquero]

My bad yet again, i forgot to tag it. Try now.

[campervantime]

Perfect - works great now, thank you!
