The Hastel Smartswitch provides a reliable, long range wireless solution for remotely controlling networks of switches. Each node may be individually addressed and turned on /off or pulsed.

Controlled via a rugged handheld controller or a PC interface the system can be scaled from a single gate opener, through to area lighting or even a whole towns street lighting the range may be further extended interfacing the controller to our GCOM units to enable control via a combination of GSM and wireless.

It is quite possible to control a 1000 switches from the other side of the world.


  • remote switch states are relayed back to the controller to show success of switch attempt.
  • Proprietary multipath networking for robust connectivity
  • 1 volt free input, 1 volts free output, change over current switchiing outputs.
  • Integrates with all our radio enabled equipment
  • Long range (up to 4 kilometers line of sight) between each node
  • Licence free operation on 2.4GHz (802.15.4 LR-WPAN) - see FAQ below

    • multiple inputs and outputs
    • leds for installation
    • optional mains PSU and relay.


  • How often are the transmissions?
    Typically once every five seconds
  • Doesn't WiFi interfere with your device?
    The short answer is no! The longer answer is that it is designed to co-exist. Both WiFi and the CSMA-CA scheme used on 802.15.4 look for clear spaces to transmit into and therefore avoid 'collisions'.
  • Can the transmissions be seen or hacked?
    No, the channels are different from WiFi and can't be snooped on by domestic equipment. In addition the very short bursts would be hard to capture and finally 128bit encryption can be employed.
  • The range seems long compared to my network at home, why?
    The performance of the 802.15.4 transmission is between 7 and 18 dB better than that of 802.11b. This can be directly translated to a range increase from 2 to 8 times the distance for the same energy per bit, or an exponential increase in reliability at any given range. We also use the highest permissable levels of power.
