I thought that Bounz (the new fork main dev) was saying it was only working for Windows at this time. If you are using it for other environments, it would not necessarily work. If you use Windows, I think he's good with it being considered working.
I like HG now that I've got my code working. I'm not ecstatic about a few things in the code, but I've learned to live with them. That's going to be the case for any solution that doesn't get coded by the actual user though. I wasn't a huge fan of C# when I started with HG, but it's very logical and follows the same syntax as all C code for the most part. Lua feels foreign to me even though I have a lot of coding experience (beginner to novice level) in different languages. Heck, I find Scheme more logical than Lua and Scheme is pretty terrible!
I'm not going to code really complex things with Blocky or any other visual programming language (e.g., my advanced smart lights code). As a result, if I were to switch to Domoticz I'd have to learn Lua which I have a negative feeling towards at the moment. That's likely going to kill Domoticz for me even though it looks really promising.
