HC-SR04 stopped working after 2022.12.x ESPHome

ESPHome

I have an esp32 with an HC-SR04 to measure distance. I got a notification to update it to the latest esphome (2022.12.x) and once I did, the sensor stopped updating. It shows the distance as 0.01m no matter how close/far something is to it. All the other sensors still update fine, wifi, uptime, etc. If I unplug the SR04 the distance goes to unavailable, so it seems to be reading the pins, but the values are not updating.

Here is my esp code.

There don’t seem to be any changes to the code for over a year

Can you confirm a role back to the last working version (which one was this btw?) does recover the function of the ultrasonic?

Mine is working fine on a d1_mini. Maybe checking it every second burn it out? Try a smaller timeout, default is 2m. Maybe remove it just in case?

I’m running on a hiletgo esp32 and it was working on 2022.11, I updated to 2022.12 to get the new filesystem or whatever and it stopped working. I am not sure how to roll back, I tried rolling back my addon to 2022.10 but I wasn’t able to compile anything.

also changing the timeout and the interval didn’t change anything.

Ahh. When changing the filesystem/framework, they recommend updating via USB not wifi. Can also try reverting to the framework type: arduino and see if that helps. Clicking “Clean Build Files” can help when have compile errors (in the 3-dot menu)

If that does not work, post an issue if you are 100% sure your ultrasonic sensor is not fried.

I did all that, and tried 2 different esp32s and 2 different sensors. will open an issue
