I want to change the source for my existing main kWh accumulated Feed (e.g. move from one emonTX to a different one).
The issue is getting emoncms to accept the change and not reset the accumulated value to zero. This might be related to this query Wh accumulator does not survive several reboots. Perhaps emoncms is not aggressive enough to look back for existing values or should be more aggressive in not feeding zeros/null to an existing accumulation Feed. @TrystanLea?
The original feed was from a Power to kWh process as will the new Feed.
There is almost a need for a ‘use last good value’ checkbox in the Input Processing page to force the last value from the accumulator into the processing.
