Which Smart Home radio standard suits me?

-- Wlan, Bluetooth and ZigBee at a glance and in comparison

Various wireless standards are used to connect individual smart home devices. The products offered by SIRO Smart Life exclusively use one of the three most common wireless standards in the smart home sector: Wlan, Bluetooth and ZigBee.

Which radio standard should you use? What are the advantages and disadvantages of the different standards? The 3 standards are presented to you here:

WLAN/WiFi: Without gateway and with high energy consumption

WLAN is the standard for connecting to the Internet and is available in every household. The SIRO Smart Life devices with integrated WiFi module can connect directly to your WLAN router, allowing control by your smartphone without a gateway. Advantages for Smart Home
  • Due to the WLAN available in many households, the devices are connected directly to the WLAN router without an additional gateway.
  • Since WLAN has a high data transmission rate, the additional data load has hardly any influence on the transmission speed and stability of the network.
Disadvantages for Smart Home
  • Data transmission with WiFi/WLAN consumes a relatively large amount of energy, which is why usually only devices with a permanent power supply, such as smart switches, or devices that rarely send signals, such as the smoke detector, use the WiFi/WLAN radio standard.
  • Since many WLANs operate in the same frequency range (2.4GHz), mutual interference can occur in more densely populated areas.
All SIRO Smart Life products with WiFi radio standard are marked with “W” at the end of their type designation, e.g. the SIRO WLAN plug SL00407W.
You probably know Bluetooth as the wireless connection of your smartphone with headphones or the car speaker system. It is a standard used in many areas for short-range radio, with a distance of up to about 50 meters. Advantages for Smart Home
  • Bluetooth Low Energy (BLE) technology, developed specifically for smart home, enables data transmission with very low power consumption, which is very important for wireless smart home devices powered by batteries or rechargeable batteries.
  • With Bluetooth, smart home devices can communicate with your smartphone even without a gateway if you forgo remote control. This has the advantage that the data is only transmitted internally and is better protected from unauthorized access.
Disadvantages for Smart Home
  • Bluetooth is severely limited in its range, especially with structural obstacles. Inside buildings, Bluetooth only has a radius of about 10 meters.
All SIRO Smart Life products with Bluetooth radio standard are marked with “B” in their type designation at the end, e.g. SIRO Bluetooth Thermostat SL02105B.

Bluetooth: Well-known wireless standard with low energy requirements

ZigBee: more widespread radio standard with special network structure

ZigBee is a radio standard widely used in the smart home sector. All devices connected with ZigBee can communicate with each other and thus form a self-managing, so-called mesh network. Advantages for Smart Home
  • The system requires little energy, is easy to operate and can be flexibly adapted.
  • As an established standard, it is supported by many manufacturers, some of them are very well-known, and therefore has many possibilities for expansion.
Disadvantages for Smart Home
  • In the past, there were compatibility issues due to different ZigBee protocols, which has since been resolved by using the new version 3.0. SIRO Smart Life’s ZigBee devices only use version 3.0, so there should be no problem with this for you as a user.
All SIRO Smart Life products with ZigBee wireless standard are marked with “Z” at the end of their type designation, e.g. the SIRO ZigBee motion sensor SL01604Z.
