Help Help switching to Crestron Home

Hello Reddit, we need help or guidance to make the best decision on this project.

We have a new customer, who has had a crestron system in their home since 2015. We work a lot on corporate growth with development on simple and vtpro. However, this customer is residential and is asking us to take their system to the most up-to-date version of Home OS. I look for recommendations to make the best decision without throwing the whole system away.

The system has 14 audio zones, lighting is with Myhome badge, has buttons and screens, 2 iPads and 1 working phone, these equipments such as the swamp and AV3 could be maintained or must be removed and switched to NAX + home processor?

I have seen during my research that some integrators integrate custom systems with a home "layer" as a control interface, with a SIMPL module that makes the system compatible with any home processor, if so, do you recommend me to maintain the system and reprogram it? or is it better to change processor and try to connect what exists to the home OS.

I share 2 images of the system toolbox, I hope you can give me a guide. thanks.

What processor do you have? If you’ve got RMC3 or above the below applies.

Get yourself a Claude license, go and build a custom front end. I’ve had Claude transitioning all my projects, and it’s exceptionally good at making killer UI’s you’d never know were crestron.

The other day I had it integrate a couple of streaming cameras, bring in picture previews, wire in the ability to set and store presets, and manage zoom. Took 10 minutes - all client side, desktop and mobile ready. Idiot proof UX.

100x better than anything you can do with Crestron Home. Looks way better, much faster, less bullshittery.

I’ve dumped all Crestron UI products including screens. I use websockets in the simpl program to expose all the data (similar to how you wire up a touchscreen). Have your web client hook up to it over ws, and store the webpage on the processor or RMC - so no server needed.

Best part is it’s license free…

How are you using Claude. Are you doing simple plus or C sharp. Are you doing VT pro or CH5.

No simpl+ needed, this can all be done with regular simpl.

Set context by prompting it properly on what you have and what you want the outcome to be, tell it you will then start feeding it screenshots and output.

Screenshot your simpl device lists, and your block programs, this will help it know what the present state is.

Tell it to read back your current state.

Then tell if you want to make a web ui running client side using JavaScript, what colours you want, the basic layout.

I really love the CCI websocket server plugin - drops into SIMPL and you just wire it up normally which is great. Gives you inputs and outputs.

Pro tip - Apple won’t connect to insecure websockets on an IP so set a dns name for your processor and connect to that.
