Dynamic electricity pricing in Québec : OpenHab FTW!

Hi everyone,

I’ve been using OpenHab for a few years, but this winter Hydro-Québec started offering dynamic electricity pricing (btw I am in Québec and house heating is with electricy). I installed 8 zwave thermostats and got started coding on OpenHab. The end result was impressive… I got a credit of $617, while the average return was $35. The thing is… there is very complex equation used to compute the credits, and OpenHab handled it very very well, updating thermostats (and water heater, and electric car charging) up to 20 times a day by “moving” the electricity consumption out of negative credits to positive credits hours…


This is, in my opinion, a great example of how smart homes can really save a lot of money.

A startup named Hilo has started selling a closed solution to save on Hydro’s winter credits. As you can expect, they abuse vendor lock-in and display an amazing lack of transparency and expertise. A good return for those customers was $200, but this is based on a few facebook discussions.

So I want to thank all the developers of OpenHab for making such a great system. I especially love how reliable this thing is. It never crashes :slight_smile: Clearly, very solid programming, which I truly appreciate.

I wish more people in Québec could benefit from the Hydro electricity credits next winter. Does anyone in the OpenHab community have experience with providing the general public a pre-configured OpenHab solution (say, openhabian) with integrated services for a specific task?
Any OpenHab enthousiast in Québec want to discuss such a project?
BTW coding and Linux is not a problem, its everything else :slight_smile:

Anyway, thanks again OpenHab, Happy 10th anniversary,

Sébastien

You might contact the folks over at HestiaPi. They have a thermostat that runs on openHAB.

Thanks for the post! It looks like you have made openHAB really pay for itself.

Hi Sébastien,
Is your code available for other openhab users?
Thanks for any additional info.

Yes, absolutely.

I am in the process of making this an addon, to simplify configuration. I also plan to build a better habpanel widget.
The most important part is to be able to configure it (thermostats, water heater, car charger, any thing consuming a lot of electricity that can be controlled, “status” light, …)

Interested in testing it or contribute to it? Contact me directly.

Thanks Sébastien,

I am very interested in your project.

On my side I am also working on something that include climat control for home automation.
