Batteries low - which HR80 then ?

[roydonaldson]

OK, so I'm getting messages on my EvoHome that the batteries are low in my Living Room. So, I have 2 x HR80's in the living room. How do I tell which one has the low batteries ?

Going further than that, I have 3 HR80's in my Kitchen, how will I work out which of these is running out of batteries when the time comes ?

Thanks,
Roy.

I assume the batteries in the same zone have been fitted the same amount of time? I so I would just change them both for the sake of what it costs.

You can always do it the old fashioned way - http://www.instructables.com/id/How-...voltage-using/
