Need help with nested If statements and state conditions

Hi. I’m building a parking aid for my garage which consists of a nodemcuv2, hc-sr04 ultrasonic sensor, and a strip of ws2812b LEDs.

I’ve managed to get it working but I have 2 remaining issues.

I currently have a lambda which contains multiple “if” statements to trigger the led strip to light up different colors depending on the ultrasonic reading. However, I only want this block of code to be triggered if the garage door is open. In other words nothing should happen if the garage door is closed. I believe the best way to accomplish this would be nested if statements but I’m having a hard time trying to figure out the proper way to code it. I’m beginning to question if this is even the best way to handle this task altogether. The garage door sensor is a Smartthings multipurpose sensor and is a binary “opening” type sensor that appears to be “off” when closed and “on” when open. My code compiles just fine but it doesn’t seem to respond to the garage door opening or closing.

The 2nd issue I’m having is with the strobe effect. Whenever I try implementing the effect the LED strip gets stuck on flashing red at all distance levels. I kept the effect info at the bottom of my code but removed the command to call it due to the issues. Does the effect code look fine?

Thanks

Anybody got any ideas?

3

To simplify what I’m asking…
How do I import the “binary_sensor.sheree.garage_door_sensor_contact” sensor state into an if statement so that the whole automation is triggered by the state of the garage door being “open/on”?

4

if you go to your Developer Tools and look down the state’s list does binary_sensor.sheree.garage_door_sensor_contact / binary_sensor.doorsensor show up? and if so when you activate it does the state change?

I got it! I just needed two if statements. I still haven’t fixed the strobe issue but I figured out the main problem.

this could be widely wrong, but does && work? i prefer to use appdaemon for the python as yaml is a pain to do anything

7

I’m still very new to this and coding in general. & seems to work but I had issues trying to code the additional if statements based on an external sensor. It’s incredibly difficult to find coding examples for esphome yaml files.

Try reviewing the ESPHome Cookbook page.

did you figure out the two if conditions issue? i am struggling for the same …can you help please
