New Ecobee lite Thermostat - much cheaper-

I was looking into this, but since it’s sold as used I believe it doesn’t have any warranty.

At this point, I’m hoping for a black Friday deal. the nest is gonna be on sale for 199 at most retailers including kohl’s plus $60 kohl’s cash. this leads me to believe ecobee will have something similar. I read that last year they ran a black Friday deal on their website for 249 for system plus 3 sensors.

Mine had 4 lines of dead pixels. Sending it back. I have another coming tomorrow.

You are wise to wait for a BF sale. I wish I could wait, but I have to get the heating situation worked out now in my house (that I bought this summer).

It seems like we have some thermostat experts on this thread. I’m trying to figure out replacement thermostat(s) for my system, and all my research so far hasn’t resulted in any concrete answers.

Each thermostat controls a single hydronic heater. Each hydronic heater is mounted in the wall, and has a fan and a hot water feed.

The current thermostats are King HW120 - “Intended for use as a 2 circuit thermostat controlling a circulation pump and fan on a hydronic coil heating system”. From looking at the specs, I presume it does two things when calling for heat:

  1. Tell the pump to start pumping hot water to all the radiators
  2. Tell the individual radiator to start its fan
    there is a delay between the above two operations (to let the hot water make it to the radiator before turning on the fan).

What are the chances any 21st century Wi-Fi thermostat would support this?


Hi @wenglish,

You can start by checking if ecobee is compatible with your configuration by using this tool:

Usually, ecobee is compatible with more than 90% of HVACs.

So I fail to see what benefits I get over the stock ST device settings other than control over the accessory sensor. Can you explain this to me? Maybe I missed it somewhere.


Refer to this thread to get the benefits:


The Home IQ reports are proving to be pretty useful. Having had the E3 and 3 sensors for a couple weeks, I’m glad I didn’t buy the light. I want to be able to use the Home IQ reports to see the temperature history and the follow me history. If you buy the light and use the Software to mimic follow me, you won’t get and accurate temperature history report and you won’t get any follow me reports from Ecobee. (That’s worth $30 to me.) There are other more important reports though, such as weather impact and you can still get the basic runtime data.

*I haven’t got the grovestreams reports up and running yet. This might get you even more with Yves software. . . .

The old Ecobee web page has a little more information, I think. Login and then go to this URL:

As nice as the Ecobee reports are, I’m finding that the Wireless Sensor Tag reports are more useful. I can get a great sense of how fast some rooms are heating and others are loosing heat. The WST site is extremely fast and very detailed. If I could only somehow get the heater runtimes in the reports. . . . I really wish that I had bought WST from the start.


For the Holidays, I’m bundling My Ecobee device and the EcobeeSetZoneWithSchedule smartapp for $30.

The combination of MyEcobee device and the Zoned Heating/Cooling Solution specially designed smartapp for ecobee is really a powerful bundle: SmartThings and ecobee working together for more comfort inside your home.

Interesting… I haven’t tried out Wireless Sensor Tags yet but I do like their longer range, increased accuracy and beep to find feature.

Hi Mike,

I don’t think any of the well known would work as you have a line voltage thermostat and 2 circuits. All of them either run off batteries or the C wire.

I think the newer version of the King have built in schedules.

Try contacting these guys and see what they may offer.

Also found this but not sure about it… Maybe you can contact Leviton and see. Good luck though.

They are super nice. They make all the other sensors I have look stupid. I plan to buy more soon.

You can get good reports that include more using normal sensors and groveStreams. But the groveStreams is a little pricey. I’m just playing with it now. It’s super powerful though. . . .

Thank you James. I have sent an email to King, and will also look at the Leviton.


I installed the Monthly stats app, but I don’t know where I’m supposed to see output. Also, which app do I need to use my ST sensors to average temps like the Ecobee remote sensors?


Here is my answer to your question:

The stats will appear in the graph at the bottom of My ecobee Device.


Great! Thank you.

How long does it take for this to show up? I installed all 3 apps, but the graph area is blank.


With the latest version of My Ecobee device(v5.6.6), the graph should appear immediately with your setpoints and the outdoor temperature.

However, if it will take some time (couple of days) to display the stats.

Please make sure to upgrade to the latest ST mobile app versions (v2.2.3/2.2.4) on Android (especially)… I don’t know what is your phone or tablet OS (Android or iOS)… Android requires the latest version of the ST mobile app for the HTMLtile to work properly.

If you have any other ST mobile app version or OS (e.g. Windows mobile), I cannot guarantee that it will work.


Thanks. I was on 5.5 of your DH. I haven’t seen 5.6.6 but I did have 5.6.3 so I installed that and now the graphs are showing up. Running iOS 10 and ST app 2.2.3.

Hi, If you want the latest version, I’ve indicated the procedure in my emails.

I will then send you the latest one right away.


which sensors do you recommend?
