I think I read emonTx as emonTH, as very few people now run the emonTx from batteries. It didn’t register that you were operating your emonTx from batteries.
In that case, I’d strongly advise you to go back to the old sketch that you had, and update (backdate?) the emonHub configuration to suit. The reason is, the new sketch that you’ve loaded runs the processor continuously (that’s the “CM” – Continuous Monitoring bit), so it will run your batteries down very quickly. The old sketch only runs the monitoring part for 200 ms in every 10 s, then the processor sleeps and uses only a very small current for the remaining 9.7 or so seconds, so the batteries will last much longer.
The sketch you want is this:
and the configuration you need is in the comment in the sketch itself. (Lines 61 - 69).
You edit emonhub.conf via the web browser: Emonhub → Edit Config and scroll down to Node 8. You should have exactly the same as shown in the sketch, but if not, replace any existing configuration for Node 8 with the lines from the sketch. You must not have two definitions for the same node.
You’ll have a similar power problem if you add to the emonTH, I can’t recollect seeing this reported by anyone, but quite a few of our users integrate the output of a weather station with their energy monitor, for obvious reasons. But that isn’t what you want. The usual additions to an emonTH are a second temperature sensor or a pulse counter for the LED on the electricity meter.
