I've been successfully using X-10 for 32 years now. Like many of you, I have had my share of issues but always managed to use filters and phase couplers to solve them. Again, like many of you, the last five years have seen the level of intermittent operation increase. Every new piece of electronics brought into the house usually requires another day of troubleshooting. I managed to swap circuits around in the breaker box such that all X-10 equipment is on one side of the box thereby eliminating the need for a phase coupler, but problems still occur. Of the 16 modules in use (all on one house code), 14 work all the time while the other 2 work most of the time. It's that "most of time" that drives me nuts. (By the way, our house is a little over1300 sq ft in size plus a basement so I don't think my issues are caused by excessively long runs).
Is it time to upgrade to a new technology? Insteon, Z-Wave, Zigbee, etc all sound promising, but I have no real experience with them. What, in your opinion, is the right choice if I were to decide to start over? Which, if any, of the above has a chance to be around decades from now such that spare parts will still be available?
Why is the new stuff so expensive? I have typically paid $10 - $15 for X-10 modules. (Although I have to admit that has been true all these years in spite of inflation). The new stuff seems to cost $50 to $70 per module. I just retired so I'm watching my spending... $69 is a lot of money for a wall switch. Multiply that by 16 or so modules and add a few controllers (manual controllers and a computer interface) and we are talking a lot of money. Maybe I should just buy a few more X-10 filters ;-)
If I stay with X-10, do the signal boosters I see discussed here really work? Many of the devices are designed to solve the cross-phase issue which I don't have (as stated above, all my X-10 equipment is on one phase). While I do believe my problems are caused by low signal levels rather than noise, I believe the low signals are caused by each new electronic appliance cutting the signal just a little more. There isn't any one thing I can unplug which solves all the issues. Filters have solved the big issues (eg, Sony TV's), but I'm guessing that many minor issues are now adding up to an overall marginal situation.
What would you do? Thanks in advance for your opinions! Pat
