So far I am pretty happy with the iAqualink. Only a few issues:

1. The Schedule interface is buggy. If you mess up a Schedule and the interface doesnt like what you did (for example, not saving) I have got a permanent "lost connection issue" and it needed a power off reboot.

2. The fonts in the scheduler dont fit, and you get a warning "Turns off after 30 Minutes" which it jams into the AIR BLOWER display and messes up the whole screen.

3. If you want something on "all the time" it doesnt like handling that in the scheduler.

4. Havent figured out how to keep the SPA HEAT in Off mode. It comes on standby when it wants.
(workaround, keep the SPA HEAT set to a low temp, them adjust when you use it.)

5. Sometimes the time/date gets confused. My "Weekend" LIGHTS ON sometimes happens on Monday or Tuesday.
