I'm trying to query the battery level of Powr Savr devices using the telnet protocol, and I haven't made sense of the return values. I mostly get back 1, which I assume is "good", but I sometimes get back a 3.

The documentation mentions:

Code:
Get (?) battery status 22 1=Normal, 2=Low
while running "?HELP,?DEVICE,22" mentions:

Code:
FORMAT: status <0-NOT BATTERY POWERED, 1-DEVICE_BATTERY_STATUS_UNKNOWN, 2-DEVICE_BATTERY_STATUS_GOOD, 3-DEVICE_BATTERY_STATUS_LOW, 4-DEVICE_STATUS_MIA>5-DEVICE_STATUS_NOT_ACTIVATED>
neither of those is consistent with 1=good and 3=anything. I suspect the documentation values are correct, but then what's 3?
