Switch State On Boot

[wiredcharlie]

I have a physical toggle switch as an input. I want to be able to read the sate of the switch onboot.

Experiment:

Code: Select all

On System#Boot do  

    If Pump#State=1
           7dtext,On
    Endif
   If Pump#State=0
           7dtext,Off
    Endif
Endon

No output! The switch has no state until it reveals itself by changing state?

Have you enabled "Send boot state" in the switch-configuration?

It is not sure that the Switch plugin or 7Segment plugin are already initialized at the System#Boot event, so you might want to wait a little, for an event that will occur a bit later:

Code: Select all

On WiFi#Connected do  
    If Pump#State=1
           7dtext,On
    Else
           7dtext,Off
    Endif
Endon

Also simplified the code a bit, using 'else' instead of another 'if'.

Tried that - but thanks

...but I had it displaying something else from On boot and it worked.

for an event that will occur a bit later:....

... I tried a one second delay with a timer but that didn't work.

I think most folk use buttons, but this use case relies upon a pre-select, where the switch is set and then the power is switched on.

Have you tried TaskRun?

Code: Select all

On System#Boot do  
  TaskRun,1 //(or whatever the number of the switch plugin is)
Endon

On Pump#State do
 If %eventvalue%=1
           7dtext,On
 Else
           7dtext,Off
 Endif
Endon

On System#Boot do  
  TaskRun,1 //(or whatever the number of the switch plugin is)
Endon

You mean TaskRun,Pump ?

Wow, is this a thing now? Things are changing fast here....

That improvement was merged well over 2 years ago

Or you can use [plugin#gpio#pinstate#13] as direct call to read the state of GPIO 13

See: https://espeasy.readthedocs.io/en/lates ... ing-events (and then scroll up half a page)

Thanks TD-er!

That was really helpful. Also, by triggering the Monitor instruction after boot, I removed the unintended consequence of pre-setting the switch prior to power on.
