Battery Low Alarm
Hello everybody this is my first post so here goes.I have a davis vp2 running cumulusmx lastest build.The problem I seem to have is low battery alarm will not shut off on the interface after changing battery.There is no battery warning on the vp2 consule.Is there a way to reset the alarm in cumulusmx?
Has anyone else had this problem I thought it would shut off after about 12/24 hours like consule does.

Re: Battery Low Alarm
Please switch on debug and data logging, then post the log file. The code looks correct in that the alarm is reset every time a new data packet is received where each transmitter battery is flagged as OK and the console battery is above 4V.

Re: Battery Low Alarm
Thanks just switched on data logging etc see what it brings up.I will also check voltage of consule battery with multimeter even though there is no warnings on the screen.Strange one!
Also I have noticed when I start cumulusmx it says no historical data available.
Cheers Warren.

Re: Battery Low Alarm
Are the alarms only for davis network attached devices (Davis WLL devices)? I cannot seem to send log file it is saying that its to large?I reset the transmitter and got the battery low warning on the davis consule screen.At midnight the warning cleared but the warning on cumulusmx dashboard is still flashing red.
Cheers warren.
I have also reinstalled cumulusmx.I have tried to send log file through private message But I dont think it has been sent.The log file is 11MB in size.
I might reset the consule.
Thanks for your time mark.

Re: Battery Low Alarm
Have you zipped up the log file? If you have and it is still too big, then maybe prune it to only include the time span when you have had problems.

Re: Battery Low Alarm
Hi, I had the same problem with my Vantage Vue.
The solution was easy as simple, just remove the console from the power supply and take out the battery, then put the battery back in and start it up again and set the clock to the same time, the date usually remains. For me this solved the problem.

Re: Battery Low Alarm
The console battery voltage is 3.96V which is below the 4.0V threshold CumulusMX uses.

Re: Battery Low Alarm
In the future you can check your batteries by using the following URL in your browser...
http://localhost:8998/api/tags/process. ... &txbattery
Or replace "localhost" with the IP address if running it remotely.
That will give the console voltage, and the status of the transmitter batteries.

Re: Battery Low Alarm
That looks good, this is the output from my Vantage Vue.
Is it possible that this comes instead of the red Alarm LED?
Sjaak.
Now you can make it visible on the Administrator Dashboard.{"battery":"4.83","txbattery":"1-LOW 2-ok 3-ok 4-ok 5-ok 6-ok 7-ok 8-ok"}

Re: Battery Low Alarm
No, for a couple of reasons...
It is Davis VP2 station specific.
To my mind the dashboard should be kept fairly clean, the alarm is there to prompt you to go and investigate, the dashboard cannot provide every diagnostic for every issue.

Re: Battery Low Alarm
Right I have just got the low battery warning show up on the consule which is reading:"3.49".So the setting in cumulus mx needs setting to this value.Because the alarm comes on at 4.00 volts as per my first post Thu Sep 24, 2020.
You cant keep changing the batteries when they just lose half a volt.
This is just my test.I just left the batteries in till I got the warning on the consule.
Cheers Warren.
{"battery":"3.49","txbattery":"1-ok 2-ok 3-ok 4-ok 5-ok 6-ok 7-ok 8-ok"}
This is on a vp2.

Re: Battery Low Alarm
Just an observation...
Are the battery terminals clean of corrosion? Any corrosion will reduce the terminal voltage measured at the console.
I had a similar issue with a second hand VP2 console I bought, there had been a leaky battery at some point and I had to open the case to clean the recessed terminal.

Re: Battery Low Alarm
Thanks, I'll change the alarm threshold to <= 3.5 V.
