As a reminder! In February 2024 I went to August and was able to install a Home Assistant home automation box. It cost around €400 for installations, I had announced a return on investment of two years. It turns out that his investment will pay off in just over a year. As you can see in the video.
August has already made €217 in savings over 9 months.
If you haven’t seen the previous video don’t hesitate it’s very informative.
I have of course produced a complete article on the installation there too it is strongly recommended that you consult it.
Save heating thanks to home automation
Warning
We are going to prepare a Live which will be broadcast on November on the YouTube channel where I will present to you the automation of the same heating but all controlled by a Sonoff NSPanel Pro , so we will tour the Sonoff universe and be able to see the positive points but also the limits of such a system.
How did we do it
It is not enough to install thermostatic faucets and control them via an application to make this kind of savings. This is currently what the government is selling us. Well no, it doesn’t work that way. To achieve such results it is not only necessary to homeize your radiators but also the heating system in our case it is a gas boiler.
Indeed thanks to the scenarios, which are the strength of many home automation systems including Home Assistant, we will be able to turn on the boiler as we wish and above all make the request room by room. Plus everything else!
In short, all the information is available in our article published in March.

Buy Now out of DomadooAt August we decided to go with a Home Assistant Green box with a Skyconnect zigbee dongle to control zigbee modules.
But you could also go with a Sonoff ihost box with integrated Zigbee key if you want to home automation certain aspects of your home, be careful with automation which will be more difficult to configure. Indeed, the Home assistant green box is compatible with the gigantic Home assistant universe and what’s more, you participate in the opensource project by investing in their Boxes and keys, and I find that nice.
For thermostatic faucets, the choice is vast but having been able to compare some, we selected the Sonoff TRVZB for its many advantages and its ease of use!

Buy Now out of IteadThen you will need a dry contact module which will control the open/closed function of your boiler (Gas, Oil and even heat pump), there are several on the market, I selected the module Nodon multifunction SIN-4-1-20 because it is very well made, moreover you can read a review on this subject.
Finally, I strongly advise you to equip each room with a micro-temperature module,** Why: The thermostatic faucet is equipped with an integrated thermostat however the temperature is distorted during operation due to the proximity to the heating body, moreover it is even more relevant when you have two radiators in the same room.
In the range of thermostatic micro-modules the choice is vast, I recommend another module Sonoff the SNZB-02P, it is reliable, aesthetic and inexpensive. here too I tested the Sonof SNZB-02P, don’t hesitate to consult.

Conclusion
This is a conclusive assessment if you still have doubts then we won’t be able to do anything for you 😁. However, there are quite a few ways to get there and above all it works without changing your traditional heating system so the return on investment is almost immediate. It’s up to you what you plan to do.
