If you have an alarm system, weather station, or something else with serial input/output that you want to integrate into your home automation system, SeriaLinc might be just the thing you need. It's a tool, so be prepared for rolling up your sleeves and doing some of the work yourself, but being able to bridge RS-232 and INSTEON is a great development. It's nice to see that more and more specialized INSTEON modules are becoming available.
