While not strictly Smartthings related, I would like to tap the Home Automation hive mind on how to proceed with an unusual project:
We recently moved into a house, custom built in the early 70’s for an IBM electrical engineer. One of the (many) unique and somewhat cool features of this house is a circa 1972 DIY home automation system. The UI is rotary dial, and the back end is relays and pulsed controlled stepping actuators. While extremely complex, the system is beautifully engineered, and still largely works 40 years later. There are several controllers (period correct smart phones - ie rotary dials with codes for various lights/scenes) and a many of our wall switches are actually 28VDC momentary switches.
Anyway, occasionally a relay gives out, or one of the logic control boards (logic all implemented on plug in cards with low voltage relays) gets hung up which can be a pain to troubleshoot, and parts are becoming scarce. I would like to upgrade the system to a more modern version of HA. This is why I have been playing around with smartthings in the more recent and conventionally wired parts of our house. The issue is that most of the light switches have 22AWG twisted pair, and all the line voltage wiring for our various fixtures terminates at the relay control panel in the attic. I was thinking that at some point I could rip the relay system out (gently of course so I can preserve it under glass in the smart home museum) and replace it with either a commercial lighting control panel, or about 15 Aeon labs micro smart switches/dimmers:
Any thoughts on this? My hesitancy with the Aeon labs modules is that they may not be the most reliable solution.
The other option is a commercial lighting control panel such as this:
While this is likely more expensive, it is a much more durable solution and allows some pretty cool configurations, this would be much harder to integrate with consumer home automation.
Any other suggestions/ideas on how to replace this beast?
