Test results for Danfoss LC Z (014G0013, firmware version 1.00, wakeup interval 300 seconds; MiOS 1.5.622, Z-Wave version 3.20, Vera routing instead of Z-Wave)

Wakeup interval

Excellent Wakeup performance. Non-equidistant points (B_Danfoss) due to manual operation.

Reaction time

Left vertical scale: CurrentSetpoint, CurrentTemperature

Right vertical scale: SetpointTarget

Temperature sensor near thermostat.

Excellent reaction time (within one wakeup interval).

Power consumption

Using Sony batteries supplied with the thermostats.

Some abnormalities for KiZ_Danfoss (non-monotonically decreasing battery level, high drop on February, 27th).

Checking the wakeup interval

local danfoss_devices = { { 221, 'KiZ' }, 
                          { 218, 'B'   },
                          { 211, 'SZ'  },
                          { 107, 'WZS' },
                          {  94, 'WZN' }  }
 
function log_wakeup( lul_device, lul_service, lul_variable, lul_value_old, lul_value_new )
 
 local s = ''
 
 for i = 1,#danfoss_devices
  do
 
   if danfoss_devices[ i ][ 1 ] == tonumber( lul_device ) 
    then
     s = danfoss_devices[ i ][ 2 ]
    end   
 
  end
 
 os.execute( 'logger -t Heizung Wakeup_' .. s )
 
end
 
 
for i = 1,#danfoss_devices
 do
  luup.variable_watch( 'log_wakeup', 'urn:micasaverde-com:serviceId:ZWaveDevice1', 'LastWakeup', danfoss_devices[ i ][ 1 ] )
 end

Synchronizing the Danfoss GUI device with temperature sensors

... using a TFA 30.3133 temperature sensor (ironically, MiOS doesn't support decidegrees for Z-Wave temperature sensors).
