I still think the smart relay will be your best bet. Before even doing anything, idec has a simulator. I does require a small "development kit".
I think idec is just drawing wires. No real programming at all.
Teco is another: http://www.factorymation.com/SG2_PLR_Smart_Relay
Schneider electric has Zelio: https://www.schneider-electric.com/en/product-range/531-smart-relay---zelio-logic-sr2-sr3/
You can always do what i do when designing something, especially programming, and I've been told it's good one. it's generally not understood by management.
I tend to think in term of:
1) I have infinite resources
2) What would I like it to do.
3) What do I need it to do.
4) What do I need it to do now.
You can totally save redesigning, if you plan properly. It sometimes cost you very little money to anticipate a feature. You plan for it, but don't figure all of the costs. it might require a bigger case or a bigger power supply.
Let's say here you wanted accounting: It might be as simple as how many times was it used and when. Maybe you would like a webpage?
Ethernet? Modbus?
Right now, I'm thinking about designing a lamp controller. A 6100 Lumen dimmable LED lamp. There is Android app, hardwired and RF.
RF means no metal box for the controller. It can't be android. Oddly enough, I find having a LED on the handheld control so the control can be located, I find important. The problems I ran into is that no one knows what they are talking about. There are 0-10V dimmers and 1-10 V dimmers. The 0-10 V dimmers where less that 0.67V is considered off. The company says that a 0-10V dimmer is included. It's really a 1-10 V dimmer that they are including which can use PWM, resistance and 1-10V. Each one has issues.
The locater LED is planned to be a dual state LED which is 100% bright when the dimming slide switch is past a detent and some other brightness otherwise. I am cannibalizing a commercial dimmer. Three options are floating around in my head and one requires building a PCB. 1) Build a PCB and connect via a modular phone cord jack. 2) Use the 120 VAC built-in switch and piggyback a hard-wired wired phone cord and 3) Use another 0-10V dimmer and do the same, just no 120 VAC to switch.
#1: I don't know if it can be done with 6 conductors. I don't think the housing will support 8.
#2 and #3: should be do-able with 6 conductors. They are radically different because the 0-10 (#3) dimmer comes with an aux power supply and won;t require a relay.
The 1-10 V dimmer would have to switch 120 V. It can use a 10K pot and resistance dimming. #2 might be more reliable with a 1K POT because 10 mA wets a contact better than 1 mA. I may have bought the 10K POT prematurely.
