New Ecobee lite Thermostat - much cheaper-

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?

I bought then realized that the sensors doesn’t work with my e3 Lite (my fault but they were on sale). So I need to replace them and saw this thread. So what do these sensors do? Do they work with ST or do they ned a device handler.

Wireless Sensor Tags have their own hub. There is a community created device handler that communicates with WST. It works very well. WST has a reporting web site as well. You can get good data from it. And it’s free. . . . I have two more tags on the way.

The reporting page lets you zoom in and out, etc. The still you can download are crude in comparison. But they give you a sense. Here’s my week.

The crazy dining room temp is from the wall to the side of my wood stove. I burn fires in the evening. . . .

You can get better reports from grovestreams, but they aren’t free. WST is.

So do you just place then on a table or do they need to be plugged in?

Also, you said they need there own hub, but I dont want another hub, so im not sure if you mean you can get them to work with ST?

Hi, I have 8 wireless tags and they use CR2032 batteries… I’ve been using them for more than a year now. The batteries last somewhere from 3-6 months depending on their configuration (long range or not).

The only drawback is that they need yet another hub. The ST integration is working well.

I really like their small form factor, and the number of features they bring in a small package.

However, please be aware that support is not always there to help in case of problems. I think that the company behind them is sort of a one-guy operation.

SInce I bought your app, what do you recommend to use with ecobee 3 lite? I do not want to use another hub (another possible failure point) and I know you aren’t a fan of the ecobee sensors which I returned.

Hi @BBoy486, please refer to my previous post:


I’ve got 7 of them now. Two more just came in. I have them set to low range and low power receiver mode. And I have the hub pinging every 10 minutes. It’s set to medium mode. I’m hoping to get closer to a year from the batteries. I’ve only had some of them for a little over 2 months. The most active PIR sensor is still at 93% and I didn’t have it setup efficiently for the first month. . . . I’ll pretty upset if I can only get 3 months. 6 months would also be a little disappointing.

I have a smart sense sensor v1 will that work?

Yes, it works with any ST connected sensors.

But it won’t measure temp in another room. That’s all I really want. Measure the temp in a few rooms to normalize the house (or that room).

Hi, look at the virtual thermostat app or a rule engine like SmartRules or Core for your specific requirements…

My smartapp calculates the avg temp from many sensors and adjusts the setpoints accordingly (just like the ecobee3’s follow me feature).


Thanks and I do understand. My point was that some rooms run colder/hotter then others, so an average of all rooms would not account for this. Would it be possible in your app (I paid for it) to have the ability to isolate to one sensor instead of using all sensors and the main ecobee device?


I understand that you contributed to my DTH (My Ecobee device).

If you want to use only certain temp sensors for your colder/hotter rooms at different times of the day, then you can use ecobeeSetZoneWithSchedule smartapp which can create virtual or physical zones (with smart vents) in your home. The avg calculation can then be done on your choice of temp sensors by creating a zone which can be enabled at certain times of the day.

You should look also look into smart vents.

EcobeeSetZoneWithSchedule is available at my store:


Thanks. Your apps are good but very detailed. Takes a while to get a handle on them.

So by using @yvesracine’s app, does the Ecobee3 lite have essentially the same functions as the Ecobee3? I need to buy two new thermostats for a new build and the $139 price tag on the lite’s is looking pretty good right now. Does anyone have an comments or suggestions on why the lite wouldn’t be sufficient? Cheers!

With the Lite, you’ll be dependent on ST. That’s probably fine. Yves’ software is good. But still. Future independence costs only $30 or so more. (If you buy more remote sensors, then it’s a little more. I bought two extra. Unless you have a very sophisticated house, you’ll probably have no need for more than 3 sensors. That’s all I have. Two would have been fine.)

You’ll also loose a lot of data on the Ecobee reports. You won’t have the follow me report. I guess that’s not a big deal. You’ll still have the general system and weather impact reports. Those are the most useful. If you want room by room reports to see how they are affecting the average, you’ll have to roll your own. That’s not so hard. It is a small minus though. . . . I’m not sure what the schedule report will look like. I think it will just indicate a long hold, as the software adjusts things using holds. Again, no big loss.

If you get the normal E3, then you have options. If you buy the lite, you have something nearly as limited as a Nest on its own. You can get a lot of power from Yves software either way. If you have the lite, you are stuck with ST + Yves to get much out of the product. That’s not so bad. But I would pay more for the option to ditch ST. I did, pay more, that is. I still have ST and use some of Yves software for changing modes. . . .

So it appears the remote sensors are being unlocked in the Lite:

Same notes in the Android update. That’s pretty significant, as there is almost feature parity between the two now.

I found some comments interesting that the ecobee Facebook page has been posting. For instance, they posted links to the ecobee3 lite and saying things like “grab them before they’re gone”. Questions people asked were answered with things like “we only made a certain amount and they’re almost gone” and “stay tuned for updates”.

Sounds like maybe they’re prepping for a new product release, and the eb3 and eb3 lite feature differences will be easier to support long term is there’s not much difference between them at all.
