You should see a field leakx in archive records and loop packets where x is
the channel number to which your WH55 is assigned. The value will be 0 when
not triggered and (I believe) 1 when triggered. The Ecowitt telnet API
documentation is very, shall we say, non-specific about the WH55
non-triggered/triggered values. I can confirm the value 0 indicates the
WH55 is not triggered and I'm not going to have the household experience a
triggered WH55 just now so I can test the triggered value :). That being
said, I've just noticed an omission in the driver that will result in
archive records containing an average of the loop packet 'leak values'
rather than the most recent loop packet value as it should. You can fix
that by adding the highlighted stanzas to your weewx.conf [Accumulator]
stanza:
[Accumulator]
....
[[leak1]]
extractor = last
[[leak2]]
extractor = last
[[leak3]]
extractor = last
[[leak4]]
extractor = last
Of course if you have mapped any of the leakx fields to some other field
name you will need to change the [[ ]] contents accordingly.
The battery value of 5 indicates a fully charged battery, the battery field
for the WH55 is an integer from 0 to 5 inclusive with 0 and 1 indicating a
'low battery'. The signal level is a quasi-signal level in that it
indicates the number of the last four packets from that sensor that were
successfully received by the gateway. 4 is good, 0 is not good.
