Hey everyone! I wanted to share my recent success in configuring two DHT22 sensors on a single ESP32 board. Initially, I faced some challenges with getting both temperature and humidity readings to display properly in Home Assistant, but after some troubleshooting, everything is working smoothly now. Here’s what I learned:
-
Unique IDs Are Key: I realized that not assigning unique IDs to each sensor was causing conflicts. By adding IDs like
buddyhotandbuddy cold, I ensured that both sensors were recognized individually in Home Assistant. -
Check the Logs: The ESPHome logs were incredibly helpful in diagnosing the issue. They showed that both sensors were providing readings, which meant the problem wasn’t with the sensors themselves but with how they were configured in Home Assistant.
-
Configuration Adjustments: I made sure to specify unique names and IDs for each sensor in my configuration file. This helped Home Assistant distinguish between the two sensors and display their data correctly.
-
Testing and Patience: I tested the setup multiple times, adjusting the configuration each time based on the results. It took a bit of trial and error, but persistence paid off!
Now, both sensors are reliably providing temperature and humidity readings, and I can monitor them from my dashboard. It’s a great feeling to overcome a technical challenge and see everything working as intended. If anyone else is struggling with similar issues, I highly recommend checking your sensor IDs and consulting the logs—these steps can save a lot of time!
Happy tinkering everyone!
