Check my new data collector for ESP32. It has many functionalities including Influx and MQTT sending and low power consumption features.
Awesome project, thanks for sharing
I moved this under Showcase-category so it’s easier to find in the future
Can you please include hardware used.
Basically any ESP32 development module should work. I have tested with this https://www.aliexpress.com/item/32994910429.html and this one https://www.aliexpress.com/item/32835656466.html. All of them are using ESP32 WROOM32 module which has 4MB flash memory. The remaining flash not used by the program is used as a storage for measurements.
No additional hardware is needed.
Where do you find specifications/manuals for these?
This is good place to start https://www.espressif.com/en/products/hardware/esp32/overview
Datasheet and technical reference manual especially.
I managed to get this up and running on an ESP32 and reading values into node-red via Mosquitto mqtt broker.
I’m wondering if anyone has any suggestions for parsing this data out within node red, this is the payload I receive:
Edit, I got this sorted out by changing the MQTT subscribe node within node-red to
parsed JSON object. A debug node can then be used to reference individual objects within the payload.
