Most of your existing devices are WiFi, which is, as I said, a completely normal, predictable purchase plan. The Hubitat Hub is connected to your LAN (hardwired) and so it does have access to all of your devices.. the "Trick" is finding a driver for those devices. Unfortunately, the vendors of some of those products think they are the center of the universe and that locking others out is a brilliant idea. They are wrong, but that doesn't change the fact that drivers can't be built without hours and hours of reverse engineering.
Nest we know is in that 'pit' where they canceled all their "Works with.." program. There's many people here that dissect each announcement from Nest looking for hope.
I hadn't heard of Nexx and their Garage Door opener.. it might be niche enough that it hasn't come up before, OR, it's wifi and it went in one ear, out the other.
Cameras are challenging because of the bandwidth they consume. I have mine going into a dedicated 'server' and haven't any need to mix them into my Home Automation, but I fully comprehend the fact that they can do a better job of detecting motion, if done right.
That's my evaluation of your list.. mostly proprietary WiFi challenges. Just to say it the other way, almost anything that has an open API has a driver that can be found. I have an EtherRain sprinkler controller.. I'm betting there's no one else in this community that's even heard of them, let alone has one. But I have a driver for it I have a Honeywell WiFi Thermostat, with a Cloud based API.. I have a driver for it.
If you're not finding the community created driver for any item on your list, it's probably due to a closed/absent API. The "answer" for them is.. don't force yourself into integrating them You probably have to whip out a phone/tablet anytime you want to use them now, running a proprietary app. Leave it be and work on all the other opportunities to automate. Maybe you want to visit Ebay and get a box full of Iris v2 motion sensors. They are superb, exceptional battery life, etc. although because they are Zigbee, there's at least one or two places in your home where the signal gets attenuated too much. You'll want a plug in repeater. So add a Peanut plug or a SmartThings Power Plug into your cart and continue automating. You'll see the difference as you join different vendors via the Hub and via Motion Lighting App (built in, but you have to click to install/enable...) can get pretty usable automation running in a few minutes (at least on your 2nd one )
Good healthy discussion with relevant information. I'm no code writer myself (some PLC programming) but with a little tinkering and help from community members you'd be surprised what you can accomplish. I came from Wink because they seemed to go radio silent and the were limited in what they could accomplish. I'm glad I've made the switch and won't look back. With all the consumer access to "Smart Home" tech and everyone trying to sell you, Hubitat has been a very close to being an all in one package in my opinion. They don't do all of it as discussed above, but stay away from those devices as they're just trying to monopolize and lock you only into their ecosystem. I'm frustrated with my Nest t-stat and have removed it for this reason. Unfortunate because it's a nice little device.
You'll find the team at hubitat to be outstanding in their ability to deliver top notch support in this venue. The same guys putting on the youtube live stream constantly look at this forum and respond. One thing to be aware of and prep yourself for is that it might take a minute to get comfortable, during which you might have devices that don't behave like you expect. My wife has been frustrate with me as I figure out motion lighting, but the team just did a helpful youtube live cast that helped a lot.
A couple more feathers in their cap is your hub is stand alone, if it works today and you don't want to update to newer software don't. It will still work regardless of a mfg pulling support II head phillips hue is pulling gen 1 support in 2020). What I've found is they just keep tweaking and improving and the experience is better all the time. Lastly item is that you can do the programming (wrong word, think drop down menus and in a easy to follow interface) from whatever device you want. I much prefer the computer to the mobile device. Go over and take a look at their intro videos to see what you are in for.
Might as well give it a try, its only $75. They are working very hard to get it as friction-free as possible. But its also a performance sports car, when you are ready for it.
First, I want to say Welcome to the Hubitat Community!
Second I want to say Boo! Nice post title for Halloween!
HE definitely leans toward the tinkerer, but I too will disagree that you need to know how to code in order to use it. I don't know how to write code. I'm relying on the kindness of the talented developers in this and the SmartThings communities for easy to install code, and there sure are a lot of therm. If you can copy and paste, you can install a driver or app. You mentioned that you are using Tasker but found the setup of a Raspberry Pi and Google Assistant Relay looked too daunting. It's just perspective I guess. I have setup both a Pi and Google Assistant Relay, but when I looked at Tasker, it looked too complicated for to me to get involved in.
So maybe I can take a second look at Tasker and you can try setting up a Raspberry Pi to start. Then if you find that's not too hard, give Google Assistant Relay a shot.
And with that advice, I will say what have you got to lose by trying Hubitat for 30 days? You can order here from Amazon and if it doesn't meet you expectations, you return it. The cost to you will be $0 and a bit of your time learning something new.
I'll give you my experience coming from the Wink hub. I think a lot of people will come across hubitat when they start hitting the limitations of google home as a hub, amazon echo as a hub and even Wink as a hub and they want to be able to do even more without needing to be a coder. Hubitat does have some simple apps for controlling lights, locks, motion lighting etc. that work great and get you started, but to do anything beyond the simple stuff, which is why most people probably come to Hubitat, requires using Rule Machine (RM) which is a very powerful if-this-then-that type engine.
The possibilities of things you can do with RM are crazy. RM can be simple enough to use with simple triggers and actions but you'll inevitably want to do more complex stuff. With RM there are so many ways to do the same thing and some ways aren't necessarily the right way to do things. It's like the wild west of automations. There are all these nuances that you need to know to perform more complex tasks such as using an End-If condition in a conditional action, or using the status of changed vs just a device turning on or off, or how to properly repeat tasks or cancel tasks or wait for tasks or check for truths. So many times I have built an automation that accomplishes the job I wanted it to do but then found out how I setup things wasn't efficient and I end up with a loop that slowly bogs down the hub. There's no checks and balances to say they way you are doing something is trouble. This would also be my biggest feedback to the developers as a new user to Hubitat - RM is the reason many people come to Hubitat, there is hopefully something that can be done in the future to provide some checks and balances as to whether the way an automation is being executed is trouble or not or make RM more intuitive somehow. I understand it's a catch 22, it's powerful because it's complex and perhaps it can't be that powerful without being complex but I think making it more intuitive is where Hubitat will really start to make traction with the average home automation user who has reached the limits of google, amazon or wink as a hub.
So in short, Hubitat is super powerful and you can easy your way into it but I, personally, would only recommend it to people who see Home Automation as a hobby and something they are willing and wanting to spend some time on. You definitely don't need to learn how to code at all. I enjoy learning how to use the platform and the community here has been amazing! If you're simply wanting to integrate more of your devices under one automation platform and do simple if this then that stuff then Wink was a pretty good experience for me but it just doesn't have anywhere near the same potential as Hubitat.
Well, I got one and it just arrived, so we'll see what I think of it this weekend.
I'm interested in getting some Zigbee motion sensors to play with, can I get SmartThings branded devices and make them work with Hubitat without having the SmartThings hub? Or do I just need to bite the bullet and get both Hubs? Their motion sensors are cheaper than non-branded ones.
The smartthings motion sensors are on the supported devices list, no need for a smartthings hub. With that being said I would recommend taking a look at the centralite 3326-L motion sensors. They are used, but a great deal that many of us including myself have found to be great sensors.
There are great package deals on Lowes Iris devices (used) on ebay. There are or were sensors on there for between $5 and $10 each if you buy a 6 or 10 pack ($30-50 as a bulk purchase). Check the supported device list to be sure you get the correct versions. I splurged for the newer Iris motion sensors and paid closer to $12 each, but the older ones are much cheaper and supposedly work fine.
I have also successfully used the Iris contact sensors as well as the outlets. I bought 8 door/window sensors for $35, and two sets of 5 outlets for $100 ($50x2). There are lots of other deals if you don't mind used. I have had really good transactions with Alex_Sari and discountpros2013 with the Iris stuff.
I am also on the fence - Hubitat or SmartThings? We need to access heat and some lights remotely for a second home. Weak internet signal. Have all Z wave or Zigbe thermostats, motion, etc.
Not interested in too complex events yet, but concerned mostly about connectivity.
notwithstanding, if you have poor connectivity and require to have remote control of your home, then neither will work very well. having said that, Hubitat does not rely upon the cloud for rules and such, so it will work better than ST every day of the week.
I would say Hubitat is for you. It’s fast and super reliable and surprisingly bug free.
Most devices can port over from other hubs like mine did from Smartthings.
It is a local solution and that is its strongest asset. But it also makes connecting remotely harder. Of course you can use the Hubitat app
I unequivocally can say Hubitat is a quality product and it blows away the competition
don’t worry ... you won’t need to write a line of code.
I lost track of how many "unsupported" devices I got working by using ST code. I think my Yamaha NVR was one such item. Good luck finding that code now. MyQ, WeMo, etc. All from ST projects. No Hubitat drivers yet, look for a ST one and see if it need fixing.
From personal experience, I know that @armand's code works with Roku streaming players.
Also, far be it from me to stop you from expressing yourself, but reviving threads from 1.5 years ago (or longer) isn't particularly useful for anyone.
Wooohoooo! It works. It took about 1/2 second to find my Ultra using the App and then probably less then minute to do the rest. Watching a very serious episode of The Pet Collective for few minutes to unwind. I just got the Ultra today. I am waiting for Power Transformer to arrive from Amazon so I can repair a light ballast. I have my doubt it will get here as promised.
The "answer" for them is.. don't force yourself into integrating them 
Nice post title for Halloween!
