uecho 0.8.5

The uecho-py is a portable and cross platform development framework for creating controller applications and devices of ECHONET Lite for Python developers. ECHONET is an open standard specification for IoT devices in Japan, it specifies more than 100 IoT devices such as crime prevention sensor, air conditioner and refrigerator.

Installation

You can install uecho-py using pip as the following:

Examples

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> <property (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)
