So here’s another blast from the past, a set of instructions for installing my xAP FHEM gateway on a Linksys NSLU2, affectionately known as a “Slug”!

FHEM allows me to control my heating system which uses the FHZ family of products (commonly sold as HouseHeat, ELV, Conrad, etc).

With the xAP FHEM gateway control and reporting is extended to the xAP network allowing interoperability with all manner of other systems.

If you already have FHEM up and running, you can just grab the download:
