I’m interested in using this to see some info from things like Nest, Google Home, Ring, Hue, etc. Unfortunately, it seems like some of them are locked down/unavailable (I’m looking at you, Nest). I was hoping we could share here ways to at least read if not write some of these devices via HTTP or something.
I’ll start: Hue has a decent API that I believe is still working. Haven’t actually tested it yet but it looks good, and I can confirm the debug endpoint works on my own Hue bridge.
I was running into similar issues when I started to dig into things last night for connecting to my devices as well. I did find this for nest, though sounds like it will be a little bit(late 2020) before any approval or access will be granted.
Hue should be pretty solid; it seems pretty well supported across home automation solutions.
The Home Assistant project has a pretty good list of (OSS) integrations - they’re all written in Python, but some of the code may be transferable to Ignition, or form a starting point for Ignition modules:
Personally, I don’t have any smart devices or I probably would have already written drivers…although if anyone wants to rectify the first problem, I could probably find some time 
Nice, I’ll take a look at that tonight! Also it seems like MyQ garage door openers should be simplish to access from what I saw last night, as well as the Tesla API.
Samsung SmartThings or Wink or any of the Zwave controllers would be a great integration.
VeSync and Sonoff have easy APIs
Add Hubitat to that list. It would be great to be able to monitor and control the connected devices of these platforms. I know Ignition Maker Edition was just release, but I am gitty with the possibilities. Ignition IS the best!
Update: Already figured it out, may not be the best way, but it works. On Hubitat, install the Maker API that is included, select which devices you want exposed, and use httpGet commands to monitor and control devices connected to the hub. Z-Wave, Zigbee, WiFi, anything connected to the Hubitat hub. I can’t wait for what the smart people figure out on connecting home components.
So i have some Hue bulbs and the API debug tool works but when I run a script in Ignition i get some errors. I am using this on the perspective button. Action performed event. Any help is much appreciated lol.

Did you configure it to use HTTPS or did it come that way? It must be a self-signed certificate; you’ll need to get a copy of that and add it to Ignition’s trusted CA cert list.
edit: or use bypass_cert_validation=1 parameter when creating the client.
I just took the s off and it worked. Should i go through the trouble of adding the certificate?
Meh, for your home network if you can just use HTTP I wouldn’t bother…
Awesome, now i just have to figure out what to do with this JSON string haha
Now I kind of want to build an OPC UA server that talks to the Philips Hue bridge/lights… and I actually have some of these.
that would be awesome because i am having trouble using this api in ignition again. I can’t get this group of lights to turn off/on.
requests = client.put(url="http://myHueIp/api/{}/groups/1/action".format(userName),data={"on":false})
the data is in the the same format in the API debug tool message body.
This is the error i get, i have tried putting false in quotes so its a string , using a 0 instead of false etc. Nothing else works. the api debug tool only accepts the word false with no quotes. there has to be something simple i am missing here haha
I even tried defining false as a variable before as 0 and “false” both did nothing

Yup that was it. haha. Thanks
