X10 ( https://en.wikipedia.org/wiki/X10_(industry_standard) ) isn't directly related to Linux, but this seems like the right group to ask about it ... I've been happily using X10 transmitters and receivers to automate switching lights on and off around my place for about two decades. These days that requires a USB-to-serial converter cable, but otherwise works just fine. X10 has significant limitations (unencrypted, local interference, very slow, one-way) but works well for the simple things I want it for. Which leads me to my two related but rather different questions. First Question: Does anyone have any X10 gear they'd like to get rid of? I'll happily take it off your hands. If you'd prefer to sell it rather than giving it away, we can talk. I'm particularly looking for a "Transceiver Module." I can still buy these from x10.com - but they're an American company without a Canadian customs broker. They'll happily ship me stuff ... but whether or not it arrives, how much I have to pay in duties, and whether or not I have to travel to Niagara Falls to pick it up ... all my problem. Second Question: What's a more modern replacement for X10? Keeping in mind that I have several limiting caveats. The first of which is, no "calling home." All interactions should happen within the confines of my computers and my residence. I would also fairly strongly prefer not to rely on a local wireless network: I have wireless, but it's deliberately off most of the time and I prefer it that way (for misguided security reasons, not misguided health reasons ... I like wires). I also don't want to have to do my own soldering (I'm capable of it, barely, but would prefer plug-and-go). Thanks. -- Giles https://www.gilesorr.com/ gilesorr@gmail.com
