[edited] Tosh, part way through looking at this the log rotated and I’d forgotten to copy it. It doesn’t add up (literally)! Also note Emoncms log is in UTC, emonhub & graphs in BST.
The Wh accumulator did not survive several quick reboots (emonTX CT channel stopped reporting after reboot).
Not sure how it does try to recover - does it look back on previous data? Should it simply discard zeros? @TrystanLea
Actually, I have just realised that the Pulse sensor is still sending the right number so why has the Wh accumulator reset???

You can see the pulses sent increase but the accumulator resets
There were 40s of zeros recorded - interestingly, no missing data despite the Pi reboots. Data sent via MQTT from Pulse sensor Pi to the Broker on this Pi.
Another observation - I multiply the output from the Wh accumulator by 0.001 and pass it to the kWh accumulator
More ‘zeros’ recorded for the kWh feed than the Wh feed.
