If by āhubā you are referring to sensors paired directly with the Echo Plusā built-in Zigbee radio, then you are correct. There is no way for any Iris v1 devices to be paired directly with the Echo Plusā Zigbee radio. Since Amazonās skills do not support temperature sensors to be integrated as Smart Home Devices, there is no way to use Hubitat as a means to get any temperature data into into Alexa.
Your only option is to use virtual contact sensors as has been described above.
I donāt believe Amazon supports passing temperature values via a skill, except for Thermostats. So, even if Hubitat added thermostats to their Alexa skill, the problem remains that Alexa Routines still cannot be triggered via thermostat temperatures. I have two Nest thermostats, and neither of these show up as options as triggers for Alexa Routines. @corerootedxb tried the same with his ecobee thermostat as well.
So, I believe most of the changes will need to come from Amazon side before Hubitat can do anything.
Question for you...why not just let Hubitat perform whatever control you desire? Why are you wanting to use Alexa for this automation? Is there a device which only works with Alexa, and not Hubitat?
Thatās understandable! An inexpensive way to replace those WiFi outlets with some that are natively supported by Hubitat, and will improve your Zigbee mesh network, is to pick up the following Iris v2 Zigbee outlets (and they are z-wave repeaters as well.)
Hubitat's Alexa skill has not added any new features recently. Thermostats are not supported, and motion/contact sensors (the most recent addition on Hubitat's side) only pass open/close information and not temperature--the addition of which for these devices was, I think, a relatively recent addition in SmartThings (I always used a few virtual thermostats to work around this limitation).
It sounds like you have SmartThings. In that case, I recommend passing your desired contact sensors to SmartThings via HubConnect (probably what I'd recommend now) or Other Hub (not sure if it supports temperature on contact sensors). Then you can integrate them via the SmartThings Alexa skill and do what your heart desires.
(And apparently you no longer have to use virtual thermostats to get what you want there, something I had been doing for a while.)
I did have ST for a month and when it didn't satisfy me with the speed of custom devices (cloud computing) I moved to Hubitat.
I also don't think it is logical to have two SmartHome hub in a home.

Which can be added as a new feature.
I also don't understand why these app code in Hubitat are private.
It can evolve way faster by making the code public and let other contribute.
Regarding this: "I donāt believe Amazon supports passing temperature values via a skill, except for Thermostats." I just got a YoLink hub that came with 2 door/window sensors, and also bought a separate Temperature+Humidity Sensor. I got this because I've been having a tough time finding a contact sensor with enough range to reach my mailbox. The YoLink uses LoRA, which supposedly has much longer range than Zigbee or Z-Wave. I haven't actually gotten around to testing that part, but I did just test out the Temperature+Humidity sensor along with their Alexa skill. Lo and behold, I can ask Alexa, "What is the Office temperature", and it will respond with the temperature on the YoLink sensor. I can't seem to access Humidity this way, but it is working for temperature. So, it seems it should be possible for the Hubitat skill to also support this. This is the sensor: Robot Check
Yes, these days the Alexa Smart Home Skill has added support for temperature sensors. I believe I read in a recent post from a Hubitat employee that the Hubitat Alexa Skill will receive some updates in the next Hub firmware/platform release. Hopefully this functionality is being added.
I've always been able to ask for the temp and create routines using temp. The problem was the actual temp wasn't showing up in the Alexa app.
I picked up the Yolink set and temp/humidity sensor a couple of months ago. The devices work well, but the app is awful. It won't show the temp history and the sensors don't report when no motion detected. This hardware and app are pretty much in the Alpha stage.
Iām mostly just hoping to have it announce when someone opens the mailbox. I donāt expect to need that for any other automation, so Iām Ok with having a 1-off solution for it. I figured Iād try the temp sensor, too, while I was at it. But if the Hubitat Alexa skill will get temp sensor support soon, Iāll hold out on getting more temp sensors. For many locations, Iād prefer a sensor that has a display, but then Iād like it to look decent, too
I use a handful of the Centralite Zigbee temp/motion detectors around the house and I'm able to query Alexa to report the temperature on various floors, in the garage, outside, etc. So as of 2021 all the Hubitat & Alexa integrations seem to be in place,
