Transmitter Battery Status

[Antonis Katsonis]

Hello!

I own a Davis Vantage Pro2 wireless weather station. The ISS channel is 1. If I want to see the condition of battery, the tag is txBatteryStatus.

What is the tag of the Wireless Leaf & Soil Moisture/Temperature Station( channel 2 )?

[Thomas Keffer]

The observation type txBatteryStatus is a bit mapped number.  The lowest order bit is  the ISS (channel 1); the next highest bit is channel 2, etc. So,

low battery for the ISS is 0x01.

For channel 1 it is 0x02.

For channel 2 it is 0x04.

and so on. I may be off a bit, but it is something like that.

being a thick ignoramus and pedant -

so 0 = all ok

1 = iss low

2 = channel 1 low

3 = channel 1 and iss low

4 = channel 2 low

5 = channel 2 and iss low

6 = channel 2 low and channel 1 low

7 = channel 2 and channel 1 and iss low

is that what u mean??

[Thomas Keffer]

Yes, although I may have the mapping off by a bit.

Oh, one other thing: it takes a long time for the battery status to register. If you want to test the bit mapping, wait about 30 minutes after taking the battery out. Same with putting it back in.

Hi Thomas,

How do you map the battery status in the following scenario? Is any guide for follow?

TRANSMITTERS: 

      Channel   Receive   Repeater  Type

         1           active       none         iss 

         2           active       A               temp_hum (as extra temperature 1 and extra humidity 1)

         3           active       A               temp_hum (as extra temperature 2 and extra humidity 2)

Thanks in advance.

This is really a Davis, not WeeWX question, but I believe they map to the transmission channel.
