A safe home for a few hundred: Tesla smart siren helps protect from just 425 CZK

Looking for a way to increase your home’s security without having to invest thousands of crowns in a professional security system? The Tesla Smart Sensor Siren is now available at an exceptionally advantageous price 425 Kč, representing a 50% discount compared to its regular price. Let’s take a look at what this affordable security feature offers and for whom it is an ideal choice.

Alza currently offers the best price on the market

The online store Alza is currently offering the Tesla Smart Sensor Siren at half the usual price. Instead of the original 849 CZK, you will pay only 425 CZK if you use the discount code ALZADNY50, which will be automatically applied at checkout. This is the lowest price for this product on the Czech market, and given more than 500 units sold, it is clearly a popular model among customers.

What does the Tesla Smart Sensor Siren offer?

This smart siren represents an effective security feature that can alert you to potential danger in several ways. Upon detecting a dangerous situation, the siren triggers an audible alarm up to 100 dB, a volume comparable to a helicopter – so you certainly won’t miss it. In addition to the audible signal, the device also activates red warning backlighting and immediately sends a notification to your mobile phone.

The siren operates on Zigbee technology, known for its low energy consumption, network stability, and a range of up to 50 meters. For its proper functionality, a Zigbee gateway (Tesla Smart ZigBee Hub) is required, which serves as a central unit connecting all smart devices in the home.

Thanks to the Tesla Smart application (available for Android and iOS), you can easily connect the siren with other smart devices and create various automations. The siren can thus automatically react to, for example:

• Opening of a window or door (in conjunction with a door/window sensor).
• Detection of unauthorized persons’ movement (with a motion sensor).
• Gas or water leaks (with appropriate detectors).
• Smoke or fire detection (with a smoke sensor).

What do customers say about the siren?

The Tesla Smart Sensor Siren has a very good rating of 4.5 out of 5 stars from 28 users on Alza. A full 82% of customers recommend this product, and the return rate is only 0.17%, which indicates high reliability.

Among the most frequently mentioned advantages are:

• Sufficient volume, ensuring you won’t miss the alarm.
• Instant reaction to stimuli, ensuring you are immediately informed of potential danger.
• Elegant design that fits into various interior types.
• Easy pairing with other devices, including the possibility of integration into the Home Assistant system.

However, users also mention certain shortcomings:

• The backup battery lasts only one to two days, so the device must be permanently connected to power.
• The siren offers only one sound, and even at the lowest setting, it is still quite loud.
• Some users mention problems with the Tesla Smart mobile application.

Customer Aleš from Olomouc states in his review: “Bought at a promotional price, so some features can be forgiven for certain uses. But at a higher price, I would probably choose a different model.” This rating confirms that at the current reduced price of 425 CZK, it is a solid offer.

Jan from Ostrava then highlights its practical use: “I bought the siren for Home Assistant to indicate intrusion, water leakage, or fire. It’s really loud and piercing. I’m not afraid that it won’t wake me up at night or alert the neighbors in the apartment next door.“
