I know this was posted almost a year ago but I found the thread by googling around since I've had customers ask me for the software as well and I'm sure others might be googling this too.
Before I go on my rant, I should mention that Lutron does in fact give homeowners a lot of power by letting them change scenes using the tablet apps for Android or the iPad AFTER the system is installed and running. You can also do an old fashion install using pressing and holding but it won't ever be compatible with apps or anything else. I should also mention that Lutron is the ONLY wireless system I have used that always works and looks good doing it. Nothing else even comes close, especially those mesh networks. This is a fixture of the house so if you use a Radioshack style "open" network, good luck with it working and good luck finding parts later.
The reason why I'm against giving the software to customers is multifold.
Between Lutron and Vantage, our company (which shall remain anonymous because I'm not here to drum up business) has invested 10's of thousands of dollars and many hours on training and CE courses and we're a small company. On any given day, I can be called to service a system and the Homeowner only says it's a "lutron" system. Is it radio ra classic? radio ra 2? Chronos? Homeworks interactive? Homeworks Illumination? Homeworks QS? "the original" Homeworks? Very few electricians can service all of these systems and AV companies can't replace electrical parts (legally in most areas) so add all the electrical licenses involved to the equation and realize that I'm not going to give this away for free without expecting something payment.
"But I'll buy the parts from you". Great. Unless you're buying enough parts for a big corporation, the profit margin on parts is very little because Lutron has many hands involved in distribution so I would be lucky to get 10-20% profit. Subtract income tax, franchise tax, and all the time it took to negotiate this with a difficult customer and it adds up to walking away. The way we make our return on investment is through the complete installation package and labor and future service calls.
I also appreciate Lutron not giving the software away because they have to protect their dealers. We invest a lot in Lutron and install their systems right. A customer who gets in trouble will blame everybody but themselves.
This is my favorite part. My background is computer science and it's amazing to me how much customers, especially those from a technical background underestimate the things that can go wrong. On the surface you just design the system and tell a button what to do and you're off and running. The reality is different.
Do you even know what to order?
Do you know about the wattage requirements of the dimmers? How many dimmers can you put on the system? Would you need to link two systems? Do you know the difference between electronic loads, magnetic loads, fan speed controls, relay loads, how many repeaters you need, etc?
Do you know how to wire these dimmers, links, or panels in case of Homeworks? I know of many seasoned electricians who can wire a big scary 480 volt industrial machine who can't figure out how to install a 4 way Lutron Dimmer or replace a thermostat with a Lutron/Honeywell thermostat.
Let's assume you've managed to install all the parts or had someone else do it and you want program them and someone gave you the software and you managed to figure out how to do the programming on the software. What do you do if something goes wrong during the upload? Say a dimmer didn't have light bulbs installed yet or you got a screen full of red warnings that dimmers failed. Can you troubleshoot that? What if you want to add or remove parts from the system, can you do that? I did a job with two main repeaters where during my upload someone knocked out power to the repeaters in one system and somehow part of the system became orphaned and got a different house address. After spending hours on the phone with Tech Support, it was decided to factory default the entire system. There were also networking issues (not my network) so the upload would take nearly an hour so I had to find workarounds around that and I've installed many systems and it still took everything I had so the homeowner could use their lights that night.
Can you handle all that? If you can't, it would cost you much more if you call the pros in after you're stuck. Once to factory default and undo everything you did, another to replace the dimmers you blew out, and lastly to start from scratch.
