Eqiva: SAVING SAVING
"Eqiva Thermostatic Head eQ-3 Bluetooth Smart" is a solution from the German ELV / eQ-3 conceived to replace manual thermo-valves for regulating the heat of radiators (or radiators, or radiators) with liquid - whether they are powered by a centralized heating system or autonomous - for the purpose to regulate, plan the heat emission and, ultimately, save energy and money. It is a manageable actuator (we'll see how) via Bluetooth LE.
As is known, domestic heaters they can be regulated in their temperature (and therefore in the radiated heat) by adjusting the manual valve which regulates the flow in the heating liquid unit from 0% (closed) to 100% (totally open). When the heater is set to 100%, its temperature assumes that of the liquid that passes through it (which it is); lower settings obviously lower the temperature.
With the advent and theappof the legislative decree 102 / 2014 which it introduces the obligation of accounting for heat for condominiums with central heating, each radiator is counted in its energy absorption: the energy bill of each apparming is given by the sum of absorption of the individual radiators based, of course, on their adjustment. THE heat meters they are in fact small anti-burglary devices placed in contact with the radiator which cyclically communicate the heat consumption of the unit by radio to a condominium plant.
It goes without saying that the consumption of an environment can be reset adjusting all radiators to 0% (in case of absence, for example) or at least reduced "Lowering" those less useful in certain specific circumstances (rooms not used, or used less).
In case of autonomous plants the argument is similar: energy consumption is given by the temperature of the liquid circulating in the circuit, the hours of ignition and the regulation of the radiators.
Manual valves are obviously not ideal to maximize energy consumption. This is because (especially in the presence of many radiators) think of "going around" to raise / lower the valves by hand, every day, more than once a day, for at least 4-5 months a year, it is not umanamethinkable. In these cases yes prousually sees to an "average" adjustment who tries to save goat and cabbage, but remains anyway far from maximum efficiency.
at "EQ-3 Thermostatic Head Bluetooth Smart Eqiva"Intervenes proprio in this sense. Since it is actually a home automation thermostatic valve, prosee where you don't want / can do it manually: it allows you to plan at profirst home automation (via smartphone, tablet, computer) switch-on times, at what temperature adjust the radiator and what to do in case of absence of the occupants of the environment. Obviously in the presence of more radiators it will be possible to place as many thermostatic heads, allowing the user a diversified planning (eg turning on the bathroom from 6 to 8 in the morning, switching back to late afternoon; bedroom from 18 to 24 etc.).
The Eqiva heads described here rappresent savings in savings because They are cheap but they allow a clear saving to be obtained from lack of energy consumption obtained through their use.
The actuator looks like a classic barrel of a few centimeters in length and width that is fitted, like all heads, instead of a traditional one. Assembly is facilitated by a standard screw flanked by various adapters supplied with the unit; if the adapters were not sufficient, the standard is easily adaptable to other valves (especially old ones) through trivial adapters that can be recovered at any hydraulic dealer.
The materials are good quality, not excellent but adequate for the purchase cost. It has a small on the front liquid crystal display which provides information on the set temperature, the chrono-programmation and other information (installation, configuration, etc.). A small acting wheel is also available both by button and adjustment ring: it is used for manual temperature regulation, as well as for navigation inside the installation / configuration menu. Two buttons (mode and menu) complete the interface panel.
First di proto see the assembly it is necessary to insert the batteries (two AA 1,5v, included in the package) - estimated duration 1 year - and configure date and time on the device; that done, you can prosee the actual assembly e proprio.
The installation it's simple and intuitive, feasible in autonomy: it involves screwing the large screw placed on the back in place of the previous manual head; if necessary, adapters are available for the various standards. That done, unity provvede self-calibration (measures the "prodepth "and the resistance of the radiator valve actuator needle), after which it is proestablished to operate.
The configuration, unlike the installation, it's a little less intuitive: the manual is not very clear and understanding exactly what to do in the first moments after installation can be complicated but, with a minimum of appthe actuator can be brought into operation.
At this point it is possible activate the proProtocol Bluetooth (LE) supported by the actuator.
What is Bluetooth for?
Simple: to connect the actuator / s wirelessly to theapp mobile "calor BT" (available for Android e iOS) for smartphones. It is a'app extremely essential, which allows you to configure the weekly, hourly and thermal head planning. THE'app, although really "minimal", it lacks nothing. The features available are:
- weekly hourly schedule / target temperature;
- instantaneous regulation of the target temperature;
- "absence" mode;
- ECO mode regulation and activation;
- function "finestra open ”(closes the radiators for a few minutes - adjustable - in case of detection of a finestopen, or collapse impronotice of temperature).
To miss, if anything, is the reading of the room temperature where the head is installed: theapp (but also the actuator display) in fact it only shows the target temperature in operation. A pity, because of the thermal sensor, obviously the unit would have, but its reading is not exposed. THE'appThe location can also register / manage several thermostatic heads simultaneously, all with different schedules, which allows to define a very punctual ignition plan.
Bluetooth LE is obviously an advantage but also a limit, as it is restricted to the maximum operating distance of 10-15 mt. between smartphone and actuator; the proHowever, the problem is mitigated by the fact that once configured the head (in the planning) it will be difficult to open theapp to make changes. It will still be sufficient to be close enough to operate, a connection that is not necessary during the functionnameordinary head. "Manual" variations in the target temperature can indeed be carried out directly on the actuator using the adjustment wheel on the front of the unit.
Obviously it is not possible to act on the actuator as a baseremotely“, But this big limit can be circumvented by using a HUB personnel. In the talk we follow.
Side note: the actuator is, in its operation, very silent. The small motor that acts on the valve needle, in fact, is well insulated from the outside.
Said soon: the degree of compatibility recognized by produttore is null.
The actuator is not in fact supported nor by Amazon Echo (Alexa), from Apple HomeKit, from Google Home (Assistant) nor even less with IFTTT.
As we will see in profirst paragraph, however, this is easily solved.
Unlike the degree of compatibility (null), that of integrability it's very high, which totally compensates for the shortcomings in terms of compatibility, allowing us to "force" compatibility. Remote control is also a possibility introduced through HUB.
"Eqiva Thermostatic Head eQ-3 Bluetooth Smart" it is indeed supported pienamefrom Home Assistant, which has one dedicated platform for full integration (GUIDA); same speech for Homebridge, which has a plugin for integration, thus making this actuator compatible Appthe HomeKits.
openHAB it is not less (available addon specific), so too Domoticz.
Nb Integration by these personal HUBdata is borrowed from the aforementioned components and proProtocol Bluetooth LE, which must necessarily be supported by the hardware at which theHUB itself is running. No proproblem for Raspberry Pi 3 / 3 + (tested by us); on Mac e Windows or different hardware requires an ad hoc focus, although we are confident that even in these environments there are no details proproblems: usually the presence of a Bluetooth adapter / antenna is sufficient. Nb
The actual possibility of integrating the head is subordinated to radio accessibility of the actuator by the Bluetooth antenna of the computer running the proprio HUB personal.
|The "EQ-3 Bluetooth Smart Eqiva Thermostatic Heads"Are interesting from several points of view. Less emblazoned with technical solutions such as the Tado Heads or other brands, these home automation actuators have from the probefore, without a doubt, the very attractive price, especially for those who have more radiators in their homes. Costing about a quarter of "noble" solutions, they allow you to domotize i profirst radiators without spending a capital.|
Certainly the level of evolution is inferior, but in terms of direct benefit - or the savings induced by the correct opening of the valves in relation to times and temperatures - it is essentially the same thing, but at a decidedly attractive price.
The compatibility level is zero, but the highest integrability with HUB personal makes this actuator a really interesting tool for those who want to optimize the proenergy absorption, especially if you want to start experimenting with home automation without spending capital.
