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 = ; var rpcClient = rpc; rpcClient;
For a full example on how to subscribe to CCU events see example.js
