Comfort Automation/ Security System Forums

I have a customer with quite an extensive Comfort system 
It did have a number of X10 lights.The customer has upgraded to Philips Hue.
I\'m pretty sure that the UCM Pi will provide 2 way communication between comfort and Hue.
What I need to know:
As an integrator I have many years of experience with comfort. However I\'ve not touched the Pi. As a one off how long is it realistically going to take me to set up from scratch a UCM Pi and program and test it to operate (say) a dozen lights with timers on/off?
I know this is open ended but I need an idea is at a day or a week - how can I justify the cost to the customer.

I suggest it is not about a cost to the customer but a cost to enhance your business and as such should be absorbed by the business. Ultimately that will then be passed on to all your customers.

I agree, it takes time to get to know Node Red, but it opens the possibilty to many new applications for customers

Yes But i run a business not a charity.
So ..... the cost has to be absorbed over time....
So how many chargeable installations can I achieve.

Once I have spent time learning how to set up the Pi the realistically how long would an installation take from scratch? This is the labour charge I would realistically put to the customer not for my many hours of learning how to set it up?
Any suggestions much appreciated?
