The uecho-py includes some sample implementations for controller and device of ECHONET Lite in the examples directory.

Examples for ECHONET Lite Controller

uechosearch

The uechosearch is a sample controller to search all ECHONET Lite nodes in the same local area network as the following usage.

  -h, --help     show this help message and exit
  -v, --verbose  output all mandatory read properties of found nodes
  -d, --debug    output raw debug messages

The uechosearch searches all ECHONET Lite device and profile objects in the local area network, and prints all found objects with the IP address as the following:

$ uechosearch
192.168.aaa.bbb [0] 05FF01 
192.168.aaa.cc  [0] 0F2001 [1] 029101

uechopost

The uechopost is a sample controller to post a message to a ECHONET Lite node in the same local network as the following usage.

Usage : uechopost <address> <obj> <esv> <"(code, data)" ...>

The uechopost can send any request message of ECHONET Lite to an object in the specified node, and print the response message. The following example controls the power status of a ECHONET Lite standard light device.

$ uechopost 192.168.aaa.bbb 029101 62 "('8A',)"  --> READ REQ (62) : Manufacture Code (0x8A)
192.168.aaaa.bbb 0EF001 72 8A 00000B             --> READ RES (72) : Panasonic (0x00000B)

$ uechopost 192.168.aaa.bbb 029101 62 "(80,)"    --> READ REQ (62) : Operation status (0x80)
192.168.aaa.bbb 029101 72 80 31                  --> READ RES (72) : OFF (0x31)

$ uechopost 192.168.aaa.bbb 029101 61 "(80,30)"  --> WRITE REQ (61) : Operation status (0x80) ON (0x30)
192.168.aaa.bbb 029101 71 80                     --> WRITE RES (71) : (No Data)

$ uechopost 192.168.aaa.bbb 029101 62 "(80,)"    --> READ REQ (62) : Operation status (0x80)
192.168.aaa.bbb 029101 72 80 30                  --> READ RES (72) : ON (0x30)

Examples for ECHONET Lite Devices

monolight

The monolight is an implementation example of the standard mono functional light device object which is specified in the ECHONET Lite, and the usage is below.

Usage : uecholight
  -h, --help     show this help message and exit
  -v, --verbose  output all mandatory read properties of found nodes
  -d, --debug    output raw debug messages

The example device object is specified as the 'Requirements for mono functional lighting class' in the Detailed Requirements for ECHONET Device objects[1], and the object code is below.

  • mono functional lighting class
    • Class group code : 0x02
    • Class code : 0x91
    • Instance code 0x01

monolight-sense

The monolight-sense is a Raspberry Pi version of the monolight and controls LEDs of Sense HAT as a mono light.
