Examples

uechosearch

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

Usage : uechosearch

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)
