Monitoring battery voltage on solar panels

Sat Jan 10, 2009 2:07 pm

Hi

I have seen on this forum that it is possible to monitor the voltage on external batteries. We have several solar powered access points that uses rb433ah router boards and would like to monitor the condition of the batteries. Can anyone tell me EXACTLY how this is done as I can find no reference to the physical connections between battery and router board.

The AH has the system health monitor which shows voltage.

Not my own code but work great!
433AH
/system health
:if ([get voltage]<120) do={/tool e-mail send server=MailserverIP to="mail@yourdomain.com.au" subject=[/system identity get name] from="mail@yourdomain.com.au" body=("Current voltage is ".[/system health get voltage])} else {:log info "Voltage is ok."}

Here is a sample of what we have running from out Mikrotiks.. all this data is automatically (every 15 minutes) accumulated and graphed for our convenience :)

Would that not require a Dude Server running all the time to get constant tracking of the voltages, or if you decided to not have a Server running wouldn't you only get the voltages at that particular moment instead of the constant monitoring?

but you could run the dude on one of your routerboards ?
so you dont need to have an extra box running ?
dont you have some monitoring running somewhere ?

We have monitoring, I agree you could have the Dude running as a Server on one of the RBs but the volume of traffic from the Dude is quite large, we try and keep unnecessary traffic like that to a minimum.

We have quite a large network so it's not necessary to have the Dude probing so heavily on the network all the time.

Can you give a screenshot of what your voltage monitoring looks like in the Dude just as an example?

Thanks for the demo.

Unfortunately the Dude just doesn't appeal

Hi All

HighOnsNow - How do you do that monitoring? I'm very interested and it will really give me a warm fuzzy feeling if I can do this.

Thanks

about the Dude usage - it is highly configurable tool and you can configure what services/values are queried.

It is possible to set up dude to only check SNMP value of voltage and temperature reading.

Just note, that some RouterBOARDS report cpu temperature some, board temperature, OID for these 2 are different.

Equis,

I am new to writing scripts in tik. Can i copy the code into text editor and put in my info, insert it in files on my rb433, and the rb will run it or is there another step?
