Tellstick & Home Easy range extender

[LiTtLe_DeE]

I have bought a Tellstick ts001 for use with a selection of Home Easy devices mostly from the Ultimate range. I have setup the devices in my living room where the PC is situated without any problems but I cannot setup my two He109 Remote Contrl Double Sockets units in the bedroom. Could they be out of range for the Tellstick unit? if yes, would the He104 Remote Control Signal Booster work with the Tellstick ts001 to extend the operating range to include the devices i have in the bedroom?

Any advice would be greatly appreciated.
