The cold is here, and the heating has been restarted to stay warm. As you know, heating is the main item of energy consumption in a health home, whether you are on electricity, gas, or fuel. However, it is possible to optimize its operation, to use the heating only when it is really necessary, which of course leads to significant savings. It is also one of the most popular used in health home automation. The health home automation solution Jeedom proposes for this an excellent thermostat plugin, which allows to create a thermostat Jeedom to optimize its heating, but also its air conditioning in summer if desired. Let's find out today how to put it in place.
I. Prerequisite to the Jeedom thermostat
To be able to optimize its heating, it will of course be necessary to control it, whether via thermostatic valves, a dry contact on the boiler, or controls via pilot wire. In my case, here I use electric radiators with pilot wire, some driven by a Zwave Qubino module pilot wire in din rail, so in the electrical panel, others via a micro pilot wire module integrated at the back of the radiator. For their implementation, I leave you to consult these articles:
It will also be necessary to provide temperature probes. Here you have many possibilities. For my part I use the temperature measured by the probes of my weather station Netatmo.
It is just as possible to use temperature probes Zwave, or even ZigBee, like those of Xiaomi found at less than 10 € for example.

Then, under Jeedom, you will need the Thermostat plugin, normally sold 8 €. A plugin fee, so, but that is well worth it, this plugin is very well thought out.
Once the plugin purchased and installed, it will of course activate it, like all other plugins.
II. Creating the Jeedom thermostat
Once the thermostat plugin installed, it will go to the menu Plugins / Comfort / Thermostat to create a device, by clicking on the "+".
It will start by giving a name to the thermostat, assign it to a room, and tick "Activate" and "Visible" to be usable. Then, on the right side, it will be necessary to choose the type of engine. Each engine uses a different algorithm for temperature regulation:
- In the case of the Hysteresis mode, the start of your heating occurs as soon as the temperature is lower than the setpoint minus the hysteresis and it goes out as soon as the temperature exceeds the setpoint plus the hysteresis. For example, if the hysteresis is set to 1 ° C and the set point is 19 ° C, then heating is activated when the temperature drops below 18 ° C and stops when it reaches 20 ° C. ° C.
- In the case of the time mode, the heating or cooling control is set to a predefined cycle and the execution time of the control depends on the difference between the setpoint and the temperature measured by the sensor. The algorithm will also calculate the heating time (or air conditioning) on a cycle depending on the inertia and the insulation of the room
This last mode is recommended, it allows to optimize comfort while achieving greater energy savings. This is the mode I selected.
Just below, you can allow the operation in heating mode, air conditioning, or both. This thermostat can also control the air conditioning. Not having air conditioning, I selected only Heating. Finally, below, we indicate the temperature range usable by the thermostat (we can not go below or above, which will prevent for example someone to switch the heating to 40 °). In my case, the terminals are set between 15 and 25 ° C.
In the following part, we need to fill in the information about the temperature probe, which will allow to monitoring the radiator. I use my indoor Netatmo probe for temperature and humidity. The time mode also requires knowing the outside temperature. It can come from a probe, or simply the weather plugin, which will recover the temperature on the internet. If you use a module that can measure the heating consumption, you can also indicate it at the bottom. But it is not obligatory.
Next is the configuration of the actions, in the next tab, which will activate the heating (or air conditioning). It is necessary to inform the actions to be carried out when one wants to heat, or to stop the heating. One can add several actions, if a thermostat must control several radiators for example. To heat, I indicate here that my electric heating, driven by pilot wire, must switch to "comfort" mode. To stop, it must go into "stop" mode, simply.
The next tab will allow us to create preconfigured modes. Commonly used modes, such as "Comfort", "Eco", "No Frost", etc. But here we can give them the name we want, and create as many modes as we want. So we create the different modes, we select in action the thermostat mode, and we indicate opposite the temperature to reach. For example here I have a Comfort mode at 20 ° C, an Eco mode at 17 °, and a Holiday mode at 15 °.
The following tab is used to manage the openings: by having a window opening detector, for example, it is possible to ask to cut the heating if the window is open more than 5min. Since my opening detectors are part of an autonomous alarm system, I can not use this function here. It would be necessary to add another compatible sensor, which would be unattractive, and my radiators integrating anyway open window detection, this is of little interest to me. But know that the plugin is able to manage it!
The following two tabs are used to manage failures, if the temperature probe is abnormal, or heating. For example, if the temperature sensor stops responding and remains stuck at 18 ° C: the heating will stay on forever as the thermostat will not reach the set temperature. In this case, if a fault is detected, we can ask to pass for example the heating in eco mode to avoid any problem, and get an SMS to be notified and take the remote hand if necessary.
If the heating is faulty, a large difference in temperature may occur relative to the set temperature. Here too we can determine a heating mode to adopt, and get a message if you want.
The last "Advanced" tab allows you to adjust certain parameters, such as cycle time, offsets, etc. It should not be necessary to change anything, but the possibility remains open.
The lower part is interesting: it is calculated by the system after a few heating cycles. These data allow the thermostat to know how much time it takes to heat in relation to the outside temperature, insulation, etc.
That's it, our thermostat is finished! One can thus create as many thermostats as zones that one wishes to manage. For my part I have a thermostat for the living room / kitchen (open), a thermostat for the bathroom, and a thermostat per room, which allows me to adjust very finely the temperature in different places.
Let's move on to its use in practice …
