When i compare my first x10 module to the ordinary ikea timers; i was really impressed with the lm465 for a couple reasons: it was dead silent, added dimming capability & of course, fancy stuff with AHP.
So, when i got a hold of appliance module- am466; i thought the improvement over the ikea timers would be silence in addition to the ability to do fancy controls with AHP.
To my disappointment, am466 clicks just as loudly as the ikea timers whenever it goes off or on. Even worse, the ikea timers had a nice "on" switch on the timer to override the timer at any time if you want it on. Because the lights i'm using don't have switches themselves...i cannot just turn the light/appliance on when i'm standing at the light/am466 module like i could with an ordinary ikea timer. This was such a big plus with a cheapo ikea timer...now i either need to invest in a remote, start up AHP on my computer (slow & i have to walk to my computer), or unplug the module & physically plug the light in..
The only real advantage right now for me to use the am466 it seems is the ability to use the dusk timer..& to be able to control the modules remotely with myhouse (although i played with that today & it seems you can only turn module on & off...so if i'm away & a module has a timer..i can't just turn the timer off?..i'll play with it more).
but, the advantage of having an "on" switch is making me consider just going back to the cheap ikea timers.
