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 sends a press and a release message.

An MBI-8 button station works like two separate dual pairs; the top four buttons send with one Radio ID, and the bottom four buttons send with a different Radio ID.

Single Paddle or Single Pair of Buttons (MBI-2)

Action Data Packet
Press ON 50
Release 00
Press OFF 70
Release 00

Dual Paddle or Dual Pair of Buttons (MBI-4)

Action Data Packet
Left Paddle or Top Pair Press ON 50
Left Paddle  or Top Pair Release 00
Left Paddle or Top Pair Press OFF 70
Left Paddle or Top Pair Release 00
Right Paddle or Bottom Pair Press ON 10
Right Paddle or Bottom Pair Release 00
Right Paddle or Bottom Pair Press OFF 30
Right Paddle or Bottom Pair Release 00

 


Sensors

Sensor Type Data  
Magnetic Contact Sensor (MC31)

EEP: A5-30-02

B4 B3 B2 B1

B4, B3, and B2 are usused

B1 = message type, contact state

  Example 1: Raw Data = 00 00 00 08 data message, Contact is Closed
  Example 2: Raw Data = 00 00 00 09 data message, Contact is Open
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
  Example 4: Raw Data = 00 00 FF 0B data message with no linked light sensor, dimming output @100%, relay closed, Occupied, repeating disabled

EnOcean Equipment Profiles A5-11-01: EEP Specification for Lighting Controller.  Page 3 explains the Lighting Controller Status.  

Note: Multi-Scene Stations (MSS) use MSC (Manufacturer Specific Configuration) messages.  The MSC telegram has the same structure as a VLD telegram but is specific to the manufacturer's implementation.

MSS 00 41 06 FF FF FF 01 00 00 Scene 1
  00 41 06 FF FF FF 02 00 00 Scene 2
  00 41 06 FF FF FF 03 00 00 Scene 3
  00 41 06 FF FF FF 01 00 00 Scene 4
  00 41 0B FF FF FF 00 00 01 ON
  00 41 0B FF FF FF 00 00 02 OFF
  00 41 07 FF FF FF 7F FF 28 Raise
  00 41 07 FF FF FF 80 00 28 Lower
