Low Battery Alarm

Post by liddelljs »

Hi all,
Hoping someone might have some thoughts on a low battery alarm I have been receiving recently on my Ecowitt GW1001 system (also have a lightning sensor and moisture sensor). When I have received these alarms, the battery display on the Ecowitt dashboard (attached) is all showing normal so not sure what is triggering the alarm. I have confirmed that the Ecowitt dashboard is normal and the alarm is still triggered when I have checked (just to verify it isn't a short intermittent fault that I missed). I have also added #lowBatteryAlarm to a realtime.txt file and it is reporting true (ie value = 1).
Are there any potential issues with these alarms and webtag on the Ecowitt systems?

Cheers
Steve

There is a fix for some battery alarm issues in the latest release - v3.12.0

If you still get issues with that version of MX, then switch on debug AND data logging for a while, then post your latest MXdiags file.

Hi Mark,
Started getting the low battery alarm again, MXDiags attached with debugging on. Looks like the culprit is the moisture sensor. Have also attached a chart of the battery voltage from the Ecowitt dashboard. I have set the alarm on the dashboard when the voltage falls below 1.5v and it all looks normal.

Cheers
Steve

OK, fixed for the next release. The data being returned does not seem to match the Ecowitt documentation :(

Sure, the email alarms still work.

Enable email logging, then look in the smtp.log file for any issues.

Ah, right with you now, the alarm web tags do not show "1" when you think they should.

Are you checking the alarm tag value within the period defined by the Latch Hours period you have set?
