system health not showing

hello
I have RB411 with V6.5 install
when I press on the health - I get no data - voltage 0.0V , so I can’t know what is the status of the power.
is this a bug? can it be fix?
do I need to install some package?
Thanks ,

Some routerboarden do not support that.
It will not be shown

which RB do support it?
and also do you think there will be a version that fix this?

Go here:
http://routerboard.com/
In the left column, select “RouterBOARD”.
Under The “Features” column, select “Voltage monitor”.

so -
I have this router - RB411U
and it’s show that he have Voltage monitor , but all I get is 0.0V
I work in 12V , does it matter?

It seems you have a malfunctioning voltage monitor. I don’t have that model to check tho. I have a couple RB433AHs and one RB433UAH, and all have operational voltage monitors.

O.k
something I can do ?

Is it still under warranty?

don’t think so

Make sure you have latest RouterOS and RouterBOOT versions installed
