Rain sensor

hello, can anyone tell me what battery numeric means. Is this the status of the battery, how full?

Usually a battery status value is a number from 0 to 100 (and displayed as a percentage). However, you haven’t told us anything about this rain sensor so we can only guess what it represents.

Tell us more this rain sensor.

it is a rain wireless rain sensor. 433mhz.
I use the RFXCOm for this.

What else do you want to know ?

I reviewed the RfxCom User Guide and found nothing that reveals information about that particular model of rain sensor or about battery attributes in general.

My suggestion would be to install a new battery and see what kind of value is reported.
