Relay With Button Actuator

Hi I had and working relay with button actuator. Yesterday I was trying codebender and after that the relay button is not working anymore. I recompile and still the same result.

@Francois

What happens if you upload the sketch using Arduino IDE again?

[Francois]

@hek it is doing the same.

Hmm.. communication looks good.

What happens if you change this:

if (message.type == V_LIGHT && strlen(msg.getString()) != 0) {

to this:

if (message.type == V_LIGHT) {

@hek thanks this is now working. Why will this happen it as it was working for more than week on the sketch in the library.

@Francois

Did it work after the change I proposed? Or by itself?

[Francois]

@hek it work with the recommendation you make.

It is possible to have more than one button and 1 really? I need 4 buttons and 4 relays. Could someone write what i should to change for that?
