binrpc

HomeMatic xmlrpc_bin:// protocol server and client

For use with CCU1/2 (rfd, hs485d, Rega), Homegear and CUxD

Implements the same interface as homematic-xmlrpc, these 2 libs
should be a 1:1 drop-in-replacement for each other.

Changelog

Breaking Change in v3.0.0: To be consistent with homematic-xmlrpc
the RPC client isn’t an event emitter anymore. All errors have to be handled through the methodCall callback.

Change in v2.1.0 To be consistent with homematic-xmlrpc you don’t
have to wait for the client connect event before using methodCall.

Breaking change in v2.0.0: system.multicall isn’t resolved in single calls anymore. This should be
done by the application itself and was removed to be consistent with
homematic-xmlrpc.

Examples

Switch on the Channel LEQ0134153:1

var rpc = require('binrpc');
var rpcClient = rpc.createClient({host: '192.168.1.100', port: '2001'});
rpcClient.methodCall('setValue', ['LEQ0134153:1', 'STATE', true], function (err, res) {
    console.log('response', err, JSON.stringify(res));
});

For a full example on how to subscribe to CCU events see example.js
