As part of my ongoing quest for a quiet life... I've taken delivery of a couple of these TRVs.
After about 30 minutes of tinkering, I'm left thinking that they're pretty much ticking all the boxes one might want, apart from Hubitat integration.
They are discrete and look fine.
The batteries are changed from the top of the TRV, just a cover that comes off. You don't have to remove the whole TRV from the radiator, like some others, then go through the process of making sure they are in the correct mode to put it back on the radiator.
This also means that people don't accidentally remove the whole think when they think it's a manual one and turn it so that the whole thing comes off in their hand. (This has happened.)
They are dead easy to operate manually - just turn them, like a mechanical TRV. A clear readout tells you what temperature you've set it to. Simple. An idiot could work it.
The app is fine - the Kasa app, which is straightforward to use and gives one a decent amount of control. It's user friendly for the average user.
App even generates usage graphs.
It was instantly picked up by the Alexa/Echo network, and works off the bat.
Basically, it's doing all I need and want... apart from Hubitat integration!
Is there any likelihood that it might come home to join the other Kasa items that are supported? Or is the fact that it works via a Kasa Hub KH100 a complete showstopper?
I have in the past used virtual contacts to "go the other way" from Hubitat to Alexa, but I don't think this is possible with thermostats? It's certainly inelegant. And introduces a cloud link.
Basically, it would be amazing if this TRV just worked in Hubitat!
It looks like in the future there may be an integration on GitHub that can be used as the basis for HE integration - but months not weeks - so that I can decode the available commands and status. There are already indications of LAN control to to the TP-Link Hub using the protocols implemented in the Kasa Drivers.
Since the device / hub are not US - I am extremely limited on what I can do. But .....
GitHub Link with information to-date (very little):
There is also the potential of a future SmartThings integration (that can then be pulled into HE using the Hubithings Replica - all in the future.
Thank you, that is all interesting. I'm keeping my fingers crossed, as so far these are the best TRVs I've come across. I can't speak for them long term, but my tinkering hitherto has not precipitated a moment of frustration or lost time. They just work, like the Kasa switches etc.
It's the dream, as opposed to the other TRVs I've used which pretty much exist to frustrate, as far as I can tell.
I am ready to work on a Kasa TRV integration into Hubitat; however, I need some assistance (as detailed below). I can not even purchase the TRV in the US.
Interested? Then respond here and I will provide app/driver links as well as instructions for step 1.
I plan on implementing commands from the User interface; however, since Hubitat has rules and schedule apps, I will not implement Kasa rule/schedule commands. I will implement settings where reasonable.
Support Required:
Step 1. Install app and HUB driver. Install HUB device. Select a single command to generate Data I need. Post data.
Step 2. Install test TRV Driver. Install TRV. Test implemented commands from driver. Run Test command that will get me data on other available commands on the TRV. Post test results, observations and data plus suggestions.
Step 3. Install new test TRV Driver. Test commands. Post data and observations plus suggestions.
