Welcome to the forum,
Your PR511 and XPS3 combination should work well together. I have three of the PR511 and I like them as security lamps.
In regard to your settings on the PR511
- When motion is detected, you are currently sending out X10 ON commands to addresses H3, H4, H5, and H6. Your putting a lot of X10 information on your house wiring that's not needed. If you only want your XPS3 (address H3) to turn on, move the switches at the +2, +3 and +4 locations to the "out" position.
- With all of the Dusk switches in the "IN" position you are sending X10 ON commands to addresses H2 - H6 as dusk and off commands at dawn. Since you want to sense motion, I'm assuming you don't want any of these on. Move them all into the "OUT" position
The PR511 may need a power cycle after changing these settings.
PR511 Manual:ftp://ftp.x10.com/pub/manuals/pr511-om.pdfThe fact that you are sometimes activating your XPS3 indicates that your hardware is functioning but the signal is not always being recognized. You mentioned that X10 looks like Greek to you. Fortunately this forum offers multiple courses in Greek.
Possible problems include:
- Powerline phase coupling problems - you could try turning on a 220V device to couple the phases as a test
- Signal absorption (power supplies, A/V equipment, PCs) - you can try turning off different breakers to isolate problem devices
- Noise generators (Compact Fluorescent bulbs, certain switching power supplies) - again, isolate by turning off circuits.
- or combinations of the above
Crash course in X10 (Greek) troubleshooting:http://www.x10community.com/forums/index.php?topic=11766.0The problems you are seeing are particular to your house. Give us an idea of the size of your home, type of electrical devices installed, whether your XPS3 and PR511 are on the same electrical phase.
