How to choose a GSM-module for remote boiler control

Our homes grow more interconnected as the world does. Heating systems are one area where this connectivity is having a big influence. The days of manually regulating your boiler are long gone; thanks to GSM modules, you can now have remote boiler control at your convenience. But how do you pick the best GSM module for your requirements when there are so many options available?

Let’s first clarify what a GSM module is. In essence, it’s a gadget that lets you operate your boiler from a distance over a mobile network, just like you can with a smartphone. This implies that you can change the temperature of your home or workplace from anywhere, even when you’re just relaxing on the couch or on vacation.

There are various considerations to make when choosing a GSM-module for remote boiler control. Compatibility is one of the most significant factors. Make sure the GSM module you select is compatible with your current system because not all modules are compatible with all boilers.

Functionality is another important component. Certain GSM modules come equipped with basic remote control features that let you change the temperature and schedule from a distance. Some have more sophisticated features like predictive maintenance, fault alerts, and energy monitoring. Take into account your unique requirements and select a module that provides the features you need.

Cost is a crucial factor as well. GSM modules have a cost associated with them even though they can offer comfort and security. While some modules might only need to be purchased once, others might need to be subscribed to on a regular basis in order to access certain features or services. When making your choice, be sure to account for both the initial outlay and any potential recurring costs.

In today"s tech-savvy world, choosing the right GSM module for remote boiler control is crucial for efficient heating management in homes. With a plethora of options available, it"s essential to consider factors like compatibility with your existing boiler system, ease of installation and use, reliability of the module"s connection, and additional features such as temperature monitoring and alerts. Whether you opt for a standalone GSM module or one integrated into a smart thermostat system, ensuring seamless communication between your smartphone and the module is key to enjoying the convenience of remote control. By selecting a GSM module that meets your specific needs and integrates smoothly into your home heating setup, you can enhance comfort, save energy, and gain peace of mind knowing your boiler is always under your control, even when you"re away.

What are GSM-modules for heating boilers

The boiler’s automation and controls can be replaced by the GSM-module, a tiny device that functions as a controller. Through cellular communication, it receives a signal and either sends a command to the boiler or, conversely, informs the boiler and heating system as a whole about its parameters and status.

What it is needed for and how it is used

Typically, the main goals of purchasing a device are to reduce costs and improve the heating system’s operating comfort. Every GSM module enables:

• switch on or completely switch off the heating boiler;
• control the temperature, for example, reducing the temperature for the time of absence for significant savings and restoring the comfort mode before arriving at the house;
• control the temperature parameters of the DHW circuit;
• coming with almost any modern module external temperature sensors allow you to more accurately maintain the temperature regime by measuring the temperature of the air in the room, not the temperature of the coolant. It is also possible to organize weather-dependent operation of the boiler.

However, safety is a very significant factor—in our opinion, even more so than price for some customers. GSM-module has the ability to alert:

• on reaching the lower or upper preset temperature limit;
• If the heating boiler is shut down due to lack of electricity or gas supply, problems with combustion products drainage, automation errors, system depressurization, etc., the system will not work properly.д. This is often a rather underrated feature, allowing you to be at peace when away for long periods of time and, in the event of a malfunction, to take timely action to prevent freezing and damage to the heating system;
• it is possible to set up notifications about temperature and other parameters of the boiler with a certain periodicity.

Depending on a model’s capabilities, alerts and control from the phone can be sent via SMS or even voice commands, a web interface, or a dedicated application. Any boiler that has the ability to connect an external control (and has the right terminals) can be connected to a GSM module. This includes solid fuel, gas, electric, and liquid fuel boilers.

The majority of contemporary models enable you to report on each of the bindings and bind at least two, but typically up to five or ten, numbers to the controller. Modern devices can organize even wider functionality because of the ability to connect additional modules to them. Examples of this functionality include controlling the pressure in circuits, monitoring the status of flow and carbon monoxide sensors, and controlling the level of liquid and even solid fuel (such as pellets in the automatic feeding hopper).

Device and principle of operation

The controller, or electronic control board, is the primary component. The gadget requires a SIM card to function; it has a slot for one. Selecting the most advantageous cellular operator and tariff is necessary, depending on the intended management and control method. The SIM card must also be regularly maintained by having its account refilled. No matter how the command is sent, it is received by the controller through cellular communication and translated into a boiler command that takes precedence over the regular automatics.

An antenna can be added to the controller to enhance communication quality. Most models have a built-in battery to ensure continuous operation during a power outage and to easily send an alert about a problem. Nearly all contemporary models are connected to external temperature sensors, both wired and wireless, the data from which takes precedence over boiler sensor readings.

How to choose a suitable model

The model’s specification is the primary criterion. Certain devices are designed as extra equipment for boilers and are only compatible with specific boiler models from a single manufacturer. Their intended use is typically indicated by the name of the device. Naturally, it is preferable to select a GSM module from the same manufacturer as the boiler (since it will be tailored for a specific line of models and their details).

However, there are also universal models that work with any boiler that has the right terminals; the article talks about these types of universal GSM modules.

There are currently only a few models of universal GSM modules available (roughly 20–25), making it challenging to discern between a sufficient number of criteria. It is advisable to examine the most well-known and prosperous models (see the examples below). below) and select one after the other, examining the features and practicality of each and contrasting costs. However, we also advise that you consider factors like:

1. Availability of application and web-interface, significantly simplifying the management, allowing you to see and analyze the statistics of work. If the manufacturer did not provide examples of the interface, it is worth looking for screenshots in the image search of any of the search engines.
2. Standard equipment. Included with some modules are external temperature sensors, which can be placed in remote from the boiler room and oriented on their measurements, which is an obvious advantage. Good is considered to be a set with a remote antenna, which allows you to seriously improve the quality of communication, and in some cases, if you take the antenna higher and even catch the missing signal on the first floor or in the basement of a remote house.
3. Capacity of the built-in battery should be at least 100-150 mAh, with these parameters it will be enough for 2-4 hours of operation of the module.

The best known manufacturers and models: features and prices

"Boiler OK"

The most widely used, best-value, and least expensive GSM module available for heating Russian-made boilers. Apart from its cost, this device is distinguished by its small size, the most straightforward setup, and the availability of an application that can send commands, including SMS, which is a great way to avoid using Internet access tariffs.

The device’s functions are fairly basic and are the bare minimum required: temperature control, alert setup, boiler parameter checking, and a built-in relay that turns the boiler on and off.

Among the drawbacks are the rather basic application with the barest minimum of features and an antiquated interface; additionally, the kit includes an external temperature sensor with a 0.5-meter cable, which does not imply that it should be installed elsewhere, away from the boiler rooms. Additionally, the antenna, which is fastened to the gadget via a threaded connection, is not remote.

KCITAL GSM 4T

Another well-known, more capable, multipurpose gadget with a far more extensive equipment list. Its heating control functions roughly correspond to those of the previous "Boiler OK"—the bare minimum—but up to four zones can accommodate extra devices (flow sensor, smoke detector, motion detector, floodlights, door opener, etc.). A reader and electronic key (like those found in intercoms) are also included in the set, allowing you to change the settings even if you can only use the electronic key.

The primary distinction is the inclusion of two 10-meter-wire-length remote temperature sensors, a remote wire antenna, and a cord for connecting an external backup battery (which, regrettably, is not built-in). Both applications and SMS can be used for control and monitoring.

The lack of an integrated battery is just one of the drawbacks; other drawbacks include the application’s large size, less appealing appearance with exposed terminals, and a low-functional and awkward but understandable interface. Keep in mind that selecting a model with the letter "T" at the end is required for heating.

EVAN GSM CLIMATE

Known by another name, ZONT H-1, it stands out for having a more contemporary and user-friendly application, pre-made "Economy" and "Comfort" modes, and the capacity to customize the boiler’s operating parameters. Once the boiler’s operation pattern has been customized, the module will automatically instruct the boiler to alter its parameters based on the time of day or the season. There is also web interface control available. includes a remote antenna and one remote temperature sensor as standard.

The absence of an integrated battery and the single contact for attaching an external temperature sensor are presumably the only drawbacks.

ZONT H-1V

An improved version of the former GSM CLIMATE (ZONT H-1). Despite its less appealing appearance, it features a built-in battery for independent operation in the event of a power outage as well as an extra "Anti-freeze" mode. Up to ten temperature sensors can be connected.

Other than that, everything is the same as the previous model because it uses the same firmware. It can be controlled via SMS, an application, or a web interface, which is among the most practical and useful because it keeps statistics. still includes a remote wired antenna and one remote temperature sensor.
