Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

HomeMatic binary RPC protocol - xmlrpc_bin://

Readme

Fork of hobbyquaker's binrpc module

This fork fixes an issue when using the Homematic app for Homey where continuous reconnects could cause the app to crash.

I recommend using the original version from hobbyquaker in all other cases.

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
