So, before I hop on here, I do want to mention that I don't have a ProfiLux controller yet. I still have a Neptune Aquacontroller (which seems horribly antiquated when compared to the ProfiLux line), but I'm hoping to upgrade to a ProfiLux in the next few months.
It's been mentioned that the View won't have a touchscreen, so as to keep prices down. It seems like most people wanted the touchscreen mainly for a feed button. What I'd like to see (and I'm not 100% sure this isn't available already) is support for simple sensors. For example, there could be simple push-button switches as an accessory, I could mount one somewhere near the tank, and when I push it, it initiates a feeding cycle. Or, I could have another switch for shutting off the lights when I introduce a new animal to my tank. It could get even more complicated, where there could be some potentiometer switches, and I could have a knob for easily changing the light intensity, or the waves, or something.
It seems like it'd be fairly simple to add something like this, and be able to access the value of the sensor in the programmable logic, and act accordingly. I think giving this flexibility to the end-users would allow us to come up with some really cool uses for it.
I would also like to see a full-fledged web server for control/monitoring, as others have mentioned on here. For those that have the device now, what I'm thinking of doing if this isn't an option, is to have a cheap laptop, connect it to the ProfiLux, and enable remote desktop to it. That way I can check on my tank/control it from anywhere (there are remote desktop clients available for iPods and Blackberries too).
I have to agree that a Telnet (/SSH?) or the option to send logging messages to a remote syslog server would be great. However, I don't really see too high a demand for this, so I'm not holding my breath. I have to disagree with the suggestion for Wireless-N (perhaps that was a joke?). Not only is 802.11 N still a draft, and quite likely to change in the future, but are 54 Mbps really not enough? It seems like this would just increase the price without *any* benefit.
Two final suggestions: Assuming the PIII will have a LAN port built in, it should have the option to connect to an NTP server, and synchronize it's clock to that. It's free, and isn't geographically restricted like the clock receiver. The second suggestion (and this too might already be in there), is for e-mail alerts. Maybe this is just limited to North American cell phone carriers, but most (all?) give the user an e-mail address for text messages to go to their phones. I think this would allow for some of the functionality of the SMS gateway (obviously it can't respond to text messages coming to the device, like I think the SMS gateway can), while also adding some flexibility.
I know that for not even having one now, that's a lot of suggestions. As a techy, I just couldn't really resist thinking about what my dream controller would have, and adding my 2 cents. I'm really excited about your line of controllers, and can't wait to see what the PIII will bring.
