How upgrade firmware from Linux

First you need to find out the IP-number of your TellStick Net, the easiest way is to check the list of attached devices in your router.

The latest firmware can be downloaded here: ​http://download.telldus.com/TellStick/Software/firmware/ Download the one named "tellstick_net_fw<version>.hex" with the highest version number.

Cycle the power to the TellStick Net and make sure the green led on the network connector flashes in groups of seven blinks. If it does it is now in recovery mode and is ready for a new firmware.
Open a terminal and type tftp -e 192.168.0.x

rexmt 1
timeout 60
put [PATH]/tellstick_net_fw3.hex

Please wait for the upload to complete, close tftp with the "quit" command.
