Device Commands

On this section we can see the commands that can be sent to the device. Whitespace and punctuation is important

The device responses are in the format: [{response_data},"ERROR"]

response_data depends on the command and "ERROR" depends on the error encountered. Error is an empty string if there are no errors.

Device state

    "serialno":"14:3", // serialno
    "disconnected":false, // connected to server
    "updating":false, // is updating
    "id":"Lab Outlet", // friendly name
    "R":{"P":26,"E":5731552,"V":227,"I":307,"Q":54}, // Readings
    "E":[0], // Events
    "O":[255], // Outputs
    "family":"14", // Device family, first part of serialno
    "version":"0.7.29", // firmware version
    "T":[[0,0,0,0,0],[0,0,0,0,0],[0,0,0,0,0],[0,0,0,0,0],[0,0,0,0,0],[0,0,-1576074900,24,0]], // Schedules
    "uptime":255360, // Time in seconds since last device restart
    "ip":"", // IP address
    "mac":"5c:cf:7f:ad:d7:8c", // MAC address
    "S":{"sS_AD":"","iS_PO":9002,"iALC":0}, // Device settings
    "untime":"1512565357.848" // Time in seconds since UNIX epoch in UTC

R is a dictionary with device readings
O is a list of output values. The index in the list is the index of the output, the output values are in the range [0, 255] and have different effects depending on the output type. For on/off outputs for example, 0 means off and > 0 means on
E is a list of events. The index in the list is the index of the event. The values in the list is the unix timestamp of the last event.
T is a list of schedules.
S is a dictionary of device settings

Device readings

P: Active power in Watts
P_: Aproximate Active power in Watts
E: Energy in Watt*seconds, monotonic
E2: Energy in Watt*seconds, Second counter (for nightly/seasonal billing), monotonic. Counter selection achieved with scheduling
Q: Reactive power in VAR
V: Voltage in Volts
I: Current in mA
T: Temperature in 0.01Celsius (2500 is 25 deg C)
GI: General digital input

Output values

on/off: 0 is off > 0 is on
range: output intensity inv/255*100 %
thermostat temperature: the thermostat set point in Celcius
thermostat mode: Thermostat mode according to the mapping below

  • 0 : OFF
  • 1 : AUTO
  • 2 : HEAT
  • 3 : COOL


iALC: allow local control allow HTTP commands on LAN
iDMC: disable manual control, any local manual output controls such as on/off buttons are ignored
iPKW: pulses per kWh as stated in the documentation of the kWh meter used
OT0: auto turn off output #0 timer in seconds, 0 for no auto-turn off


Format READ
Get device state readings(R)/outputs(O), rssi,id

[{"untime":"1551704369.267","id":"HAM 1","rssi":"-58","R":{"E":66960000,"P_":0,"GI":1,"E2":0},"E":[0],"O":[255],"family":"12","serialno":"12:152","disconnected":false},""]


Format WRITE index,value
Set the ouput state at index to value
For example WRITE 0,255, sets output 0 to 255 (fully on)


Format STAT
Get device info
[{"serialno":"12:152","uptime":442364,"version":"0.8.39","hostname":"HAM 1","ip":"","mac":"5c:cf:7f:ae:94:fe","untime":"1551707144.926","family":"12","disconnected":false},""]


Format TIMED index,start,interval,duration,output_index,output_value
Set schedule
index is the index in the Schedule table
start is the start of schedule in UNIX timestamp (seconds) in UTC
interval the interval in seconds that the schedule repeats, 0 for no repeat. High bits set weekday mask
duration the duration of the schedule, after which the output will be set to 0
output_index the output to set the value to, negative for selecting energy counter
output_value the value to set the output to


Read schedules
The schedules are read in an array of arrays where the index of the "T" array is the TIMED index, and each shedule array is in the format [index,start,interval,duration,output_index,output_value] as described above


Format SET "key","value"
Set settings


Format RSET
Read settings
