I recently bought 3 power socket and a remote from Chacon (ref. 54655 or EMW200TC/RC) which are not yet compatible with Tellstick.
It uses a SC2262 chip to encode the rf signal, opérating at 433,92Mhz, it claims to be PT2262 compatible. Some switches also have dimmer support but i don't have one.
I found some docs on the chip manufacturer site (http://sc-tech.cn/en/SC2262.pdf
This is how they look like :
The remote can operate 4 switches, you have a wheel on the back where you choose A, B or C codes.
on the switch you also have a wheel with A1 to A4, B1 to B4, C1 to C4.
I don't know if it would be posible to make the tellstick compatible, i don't know what information you need but i would be glad to help !
The tellstick is great !!! (i use it with classic chacon switch with siple protocol, chacon advanced protocol and even some elro style switch.. )
Thank you very much !
