The sandbox is a good environment to practice.

Thats great and I'm very keen to become self sufficient with this, however coming from zero working knowledge I don't know how to test scenarios in the sandbox. I tried last night at length. Could you please show me a specific example of how I would sandbox the power commands, for example?

1. Proposed solution was for the case of 8 zones input as it was presented originally.

Try this as name expression for more flexibility. Remember to use straight quotes " " ONLY.

Substring((Split(input, ";")[0]),0,5)&& Substring((Split(input, ";")[1]),0,5)&& ... Substring((Split(input, ";")[7]),0,5)

This would change only the respective zone in the case of single zone action and response.
Furthermore, it will manage other actions such as VOL for example if the responses are uniform.

For Example if you receive a response

Z4VOL15

than Big5 will create HS3 device

Z4VOL = 15

However if the responses are not uniform than you have to create different TCP for different actions.



2. Examples

If a response arrives for a single zone (zone4 in the example below) like this

Z4POW1

than what happens is


BEFORE

Z1POW = 1 (because the names were fixed and the value of the first (and only ) input goes to Name #1 which is Z1POW)


NOW with the new name expression

Z4POW = 1 (because the name is not fixed but retrieved from the input )

3. Avoid disappointments and red ink. Always test your expressions before deploying

GoTo HS3-->Plugins-->Big5-->Documentation Scroll down to the sandbox

Example:

Input box - Z4POW1

Expression box (always wrap your expression in ${....} wrapper) - ${Substring((Split(input, ";")[0]),0,5)}

Result - Z4POW

I assume your device contains:
Z1POW0;Z2POW0;Z3POW0;Z4POW0;Z5POW0;Z6POW0;Z7POW0;Z8POW0; (Put this in the variable input of the sanbox)

In the expression box you can use: ${ Substring(input, 5, 1) } ${ Substring(input, 12, 1) }

This will result in 0 0

You can also use the more sophisticated commands to do it smarter. But I suggest to go the easy way and optimize when it is working.
