emonTx Arduino Shield v2.4 usable to send data to a pi or homeassisant?

borpin:

miniterm --rtscts /dev/ttyAMA0 115200

but use 9600

[edit]
If it is not getting data, switch RX/TX as a first option.

dazzle_rsa:

[[SerialDirect]]
     Type = EmonHubSerialInterfacer
      [[[init_settings]]]
           com_port = /dev/ttyAMA0      # or /dev/ttyAMA0 or/dev/ttyACM0 etc
           com_baud = 9600              # to match the baud of the connected device
      [[[runtimesettings]]]
           pubchannels = ToEmonCMS,

looks like it should be right. - delete the other one.

Modify the pub/sub as above

restart emonhub

sudo systemctl restart emonhub.service and post the initial log.

Oh and fix SSH

dazzle_rsa · 2021-03-15T10:54:44.306Z

lol, I shall fix the ssh.

When you say post the initial log, I assume you are referring to the emonhub.log? I can get that from the gui?

Had to change the loop in the sketch, wants only numerical values, so no key value pairs:

That’s because you have the wrong interfacer for that format. You are now using the Serial interfacer that requires space-separated values; the EmonHubTx3e Interfacer requires key:value pairs.

The latter carries the name of the variable with it, the former means the data arrives and you need to interpret what it is.

Ah, my bad, I said to remove the wrong one

Thanks for all the help guys.

Really appreciate it, got it all up and running.
Hopefully, this thread will help someone else at some point.

dazzle_rsa · 2021-03-16T16:45:58.000Z

Sorry, lol. Installed it all, was running nicely, but then after a power cut, my inputs have gone to minuses. Any idea at all why that would suddenly happen?
I thought it could only do that by putting the CT’s on the wrong way around. But I definitely had positive numbers when I switched it on to test it, and haven’t taken the CT’s off since then.

My initial thought is the calibration somewhere has got corrupted. I would start at the emonTx Shield and check that the outputs from that are sensible. If that looks OK, check the numbers in emonHub.conf
