13.1 Data Telegram Type 1
Syntax:
<STX>USR1<CR><LF>
Answer:
<STX>t1:A;B;C;D;E;F;G;H*CS<CR><LF>
A = precipitation intensity in mm/min
B = precipitation intensity in mm/h
C = average intensity since last call in mm/min
D = average intensity since last call in mm/h
E = amount since last call in mm
F = total amount since system start in mm
G = status of heating (1 = ON, 0 = OFF)
H = inner temperature below in °C
* = delimiter checksum
CS = checksum (see chapter “Checksum”)
13.2 Data Telegram Type 2
Syntax:
<STX>USR2<CR><LF>
Answer:
<STX>t2:A;B;C;D;E;F;G;H;I;J*CS<CR><LF>
A = date in format YYYY.MM.DD (Y = year, M = month, D = day)
B = time in format hh:mm:ss (h = hour, m = minute, s = second)
C = precipitation intensity in mm/h
D = total amount since system start in mm (accumulated precipitation)
E = measurement Start / Stop (1 = Stop and 0 = Start (running))
F = inner temperature above in °C
G = inner temperature below in °C
H = status of heating (1 = ON, 0 = OFF)
I = error code
J = outside temperature in °C (no measured value = / )
* = delimiter checksum
CS = checksum (see chapter “Checksum”)
The returned error code is a decimal representation of an originally binary number.
In binary representation, the digits correspond to the following error messages:
Bit position Status message
0 error maximum heating temperature threshold exceeded
1 1 = error heating
2 1 = error temperature sensor interior
3 1 = error temperature sensor at the funnel
4 1 = error initialization RTC
5 1 = error external temperature sensor
6 1 = poor quality of supply voltage
