Hi scott,
Yep you will be able to control your ProfiLux anywhere in the world unlike other brands where you can just view the parameters. This is one of GHL's biggest plus points.
You will be able to set up email alerts direct to your phone, as for texting GHL use dedicated GSM devise which runs independant to the ProfiLux so even in the event of power outage the SMS module will text you to let you know, where other built in types will only warn you once the power is back on. Sort of like shutting the stable door once the horse is bolted really, not being able to send an alarm when the power goes out.
Info on the GHL SMS system can be found by doing SMS search in this forum or have alook in the catalogue thats sticky on this site.
