I know it’s not ST controlled, but I just found this new system for electric baseboard control. It ticked almost all my boxes, including being pretty cost effective. SinopeTech Thermostats
Some other opitons are Caleo that is due in January at $150 with wifi and promise of an API

SmartThings Zigbee Line Voltage Thermostat for baseboards

From the Left field and cheapest by far with PID control at the heater certified to maintain the temperature fluctuations to less than 1.5C at the room center with a smaller (but much hotter) modern design - the Dimplex Connex with an unreleased-but-mooted-in-2012 Connex to Wifi bridge. It’s about $110 at more electric per baseboard heater, and the timer is $50. The little remote is $25 but not compatible with the programmer. http://blog.dimplex.com/energy/re-inventing-the-electric-baseboard/
And the nuheat wifi which has no API (although they did mention once back on Facebook then dumped the thread) and is $250 per room with no triac control for convectors.
Seeing as this thread has found some life…
The Sinopetech Thermostats are $200 for the starter kit, which is 2 stats and the hub, and then $65 for each additional stat, making it the most cost effective I have come across.
When I called and asked about integration with other systems, all they would say is that they are in talks, with who/what system they wouldn’t say.
Those look nice and a good price point. Are they Triac or Relay?
I’m not quite sure what you mean by that, there isn’t a relay that has to be added into the circuit.
If I told you they’re only made to handle resistive loads, not inductive, would that give you the answer you’re looking for by inference?
I think that because they support a variable duration, if they can get that duration down to 15s it’s Triac. 2-15 minutes is relay.
A relay makes audible clicks.
Regarding the Caleo, I email them and they said they would be supporting ‘if this then that’ platform. Does this work with Smart Things?
Their response: “We are currently looking into home automation integration. Our current choice lies with IfThisThenThat (ifttt.com) and we should be able to open a channel there before Caleo ships in January. Hub integration will come next and since every manufacturer has come up with their own tricks, we will require time to adress all devices out there. Hubs that can pilot a web handler such as ifttt.com will be integrated right away. Those that rely on proprietary protocols will come in sequence afterwards.”
There is a Smartthings channel on IFTTT, but it’s pretty basic so it might take some creative setup to get it to talk to Caleo. I’m betting you’ll be able to make it work that way. Can’t know for sure until we see what Caleo’s IFTTT channel includes.
My Sinope stats arrived today! They’re smaller than I expected.

Why did you get the Sinope ones are they compatible with ST?
I got them because they’re the first really cost effective and “smart” thermostats I could find for electric baseboard heaters.
Hopefully they’ll become integrated with some sort of “smart” system down the line.
Can you control it from the Internet or do you need the hub?
The hub connects all of the thermostats to the net, it is required if you want to program the stats from the web. Without it, they won’t talk to each other, or the web, but you could program each one manually.
So how do you like the sinope? I am thinking of getting them as well even if it’s not going to integrate with St?
I couldn’t be happier. The only thing I’d like is a way to view the usage of all of the stats in a single page view on the website. I’ve sent a request for this to Sinope, we’ll see how responsive they are.
I haven’t looked for myself, but my wife says she’s seeing a dip in our weekly electricity usage already.

Do the sinope thermostats come with an iOS app? If so, under wich name do I find it?
No need for an app, it’s all done through a mobile responsive designed website that will work and look great on any of your devices. It’s actually one of the reasons I went with Sinope, not everything needs an app, a well designed website is just as good, if not better because it’s platform agnostic.
Here’s what it looks like on my PC
Same thing on my Lumia 1020

Here are some questions and answer from the Rep.
- is the thermostat a triac or relay control?
*** Our TH1120RF-3000 has a triac. *** - I am currently having a home automation with Smartthings system. Is there any plan to integrate your system with anyone?
*** We are currently considering opening the platform through an API on our server. However, we do not expect to open this project before Q3 2015. Would you like to be notified if we open the platform? *** - is the Internet hub mainly use for external access? Can I still be able to have control of everything with intranet on my mobile phone or computer?
*** Presently, you need to access the www.neviweb.com with either your phone, tablet or computer to manage your thermostats. In 2015, consumers will be able to manage their systems locally without having to connect to the Internet. ***
do you know roughly when will the local network control will be implemented in 2015? For now what kind of control do I have if I lost Internet for a couple of days?
We are most likely looking at Q3 2015. If you were to lose your Internet connection, the only thing that would happen is that the Outside temperature displayed on the LCD and the time would not be updated and you would not be able to change your programs. The programs that have already configured would still continue without any issues, you would not lose heat in your home unless you lose power.

First, thanks for all the details. Looks like this might be the system for me as well.
Second, do I correctly understand that there could be up to six periods per day? Can each period setpoint be controlled independently? It just so happens that in your master bed currently only 2 setpoints are used, so I can’t confirm. The reason I’m asking is because most other programmable T-state have “modes”, so technically one has a choice of 3 or 4 setpoints for all periods for all days, which limits flexibility.
Someone showed me this 230V relay-based Zwave thermostat for underfloor heating from Norway today.
