JSON field <AState>-<Reg> is a status of the device at moment when values
were sampled. Description of the status bits:
Bit
Description
bit0
– bit1
RSSI level indicator (0 = poor signal, 1 = sufficient, 2 = good, 3 = excellent)
bit2
– bit4
Unused
bit5
WLAN co-processor error (=1)
bit6
Internal hardware error (1 = Internal hardware error - RTC, EEPROM, LCD)
bit7
Device properly connected into Wifi (=1)
bit8
Optical LED active (=1)
bit9
Acoustic active (=1)
bit10
Unused
bit11
RTC time may not be valid - low voltage detected at RTC (=1)
bit12
Measurement error at one of channels (=1)
bit13
Configuration is not valid - configuration error (=1)
bit14
– bit15
Unused
Some bits at AState register can be deactivated at the configuration. Table
below shows these bits. Other bits are unused.
