Decoding the data packets of Echoflex devices at a glance

 What does the data value mean?

Monitoring the wireless telegrams is nice but the raw data doesn't real tell you anything. So how do you know what it means

What is the raw data?

The raw data is viewable as bytes and is in hexadecimal format 

For a switch station message, the data is 1 byte long. For a sensor or controller status message, the data is 4 bytes long

Switches

Switches come as a single paddle / pair of buttons or as a dual paddle / pair of buttons. Each paddle or button has a press and a release message

Single Paddle or Single Pair of Buttons

Action Data Packet
Press ON 50
Release 00
Press OFF 70

Sensors

Sensor Type Data  
Occupancy

B4 B3 B2 B1

B4 = % value of supply voltage

B3 = ignore

B2 = occupancy state [00 = vacant] [FF = occupied]

B1 = message type [any value ending in 8, 9, A, B, C, D, E, F is a data message, a value ending in 7, 6, 5, 4, 2, 1, 0 is a TEACH message]

Occupancy Example 1: Raw Data = 70 00 00 0F data message with values of 44% stored energy, vacant state
Occupancy Example 2: Raw Data = EF 00 FF 0F data message with values of 94% stored energy, occupied state
Occupancy Example 3: Raw Data = 1C 08 04 87 TEACH message with 1C 08 = occupancy sensor, 04 = manufacturer = Echoflex Solutions
     
Lighting Controller Status B4 B3 B2 B1

B4 = % light level in zone via linked light sensor [00 = no linked sensor or no light]

B3 = closed loop daylighting set point in % [

B2 = current dimming output value

B1 = message type, relay state, zone occupancy state, repeater mode state

Lighting Controller Example 1: Raw Data = 00 00 FF 09 data message with no linked light sensor, dimming output @ 100%, relay closed, unoccupied (or no occ sensor linked), repeating disabled
  Example 2: Raw Data = 00 00 00 0B data message with no linked light sensor, dimming output @ 0%, relay open, unoccupied (or no occ sensor linked), repeating disabled
  Example 3: Raw Data = 00 00 00 0A data message with no linked light sensor, dimming output @ 0%, relay open, Occupied, repeating disabled
