Have 50% of my house wall switches replace with x-10
Got few motion detectors for light (to let me know when someone close to the door or outsize...)
Got a copler and amplifier installed
Now I want to setup
1. the low voltage garden lights to some x10 system
2. the air condition + heater to some x10 controlled system
3. The 10 station water system for the garder
4. an RF repeater/amplifier so I can control it all
from anywhere in the house (at the moment it working
from 50-60 feet but I want it from 100-200feet!)

Any expirience with any of my 1-4 goals?
Any "don't do this!" sugestions?
thanks,
Shai
