X-10 Support?

Sure no problem.

So Xiaomi devices are close to the Zigbee spec, but they don't follow it exactly. So for developers this is a pain because they have a lot of design variation. However, we're so lucky to have such very talented developers that have managed to create some really reliable drivers.

The Xiaomi also tend to fall off your network unless they are either really close to the hub or you have repeaters. Because they are non-compliant Zigbee, many repeaters do not work with them. The list is short. However, the recently introduced IKEA Trådfri outlets are compatible repeaters for Xiaomi and other Zigbee devices. They're only $9, so that's another bonus, but as a result they also do not have strong radios. But they connect to each other nicely, so if you buy several of them and place them around your home, you should have a healthy Zigbee mesh. This is my experience since adding just two of the IKEA Trådfri outlets. None of my Xiaomi devices have dropped.

Insteon is about 14 years old now I think. They were bought by Richmond Capital Partners and Rob Lilleness is their new CEO. So far they haven't produced much more than they had before, but the insider info suggest they're not giving up and we can expect more from them. Honestly it's tough for me to recommend someone go out any buy their devices if they don't already own them. I'd be more inclined to recommend Lutron Caséta, which I know isn't going anywhere. There are several ways to control Insteon via cloud, but it's not 100% reliable if the cloud doesn't have a 100% up time, which it most certainly does not. Not bad, but at times it was getting some harsh feedback. Very, very low WAF.

Having said that, there's just software standing between their hub and full integration with Hubitat. It's just not a big enough user base for them to get on board with the limited resources they have at this stage, and I completely understand that position. I'm thankful that I have help from Scott Kuester who answered the call to separate the Insteondirect Express Server from Homebridge. That made a huge difference, and if it were not for the generous help from @cwwilson08 and @ogiewon, I wouldn't have the drivers needed to control my lights via the Express Server.

The insteon product actually has got a lot going for it that many competitors still cannot do.

• Dual mesh - Insteon radio mesh and an evolved X10 type powerline mesh.
• Hardware programmable - Switches, dimmers and outlets can be controllers, responders or both. They can also have their ON and ramp rates programmed in hardware.
• Some of their devices, like outlets and plug-in modules have load sensing. So for example, if I turn on my floor lamp connected to my Insteon outlet, it senses that the light is trying to draw power and turns that outlet on. This is then recognized by Hubitat and so nothing gets out of sync. Big WAF. She just uses our lights anyway she wants, and yet still has full control via Alexa.
• They have changeable face plates: For me white is just fine, but some people want other colors. They also offer ivory, off-white and black changeable faces. Leviton is one of the few others that I know offers this. Many want you to replace the whole switch or simply don't offer the option at all.

Now consider these options that typically don't come in a consumer device, or if it does you pay through the nose for it. Insteon are very cost effective by comparison. I do admit to some bias, but ever since I started using the standalone Express Server, which was the beginning of October, my Insteon lights are rock solid. Zero issues other than an old model outlet that needed replacing, and I have suspected issues with it for years. Wasn't until it started physically showing improper behavior that I knew it was time for it to go.
