Odd behavior with ESPhome button press

ESPHome
1

I have a HA automation that simply pushes 2 buttons on an ESPHome ESP32. When I perform both pushes in one automation the ESP registers the pushes but does not change the light state. When I break the automation down in to 2 automations with 1 button press each, it works every time.

          repeat:

The logs show the button presses in all cases, but when I do both together there are no error messages but the ligths do not toggle.

What in the world am I missing here?

Add sufficient delay to HA automation / set non_blocking: false on remote transmitter.

I went to non-blocking and it works. I expected non-blocking true was a good setting, you know prevent 2 things from trying to use it at a time... I guess it works that way!

I had tried delay, expecting it was a possible cause, got up to 3 seconds and still was not reliable.

But, fixed now.

It is, but not in this case. Non blocking doesn't wait for first transmission to be completed.
