ESP32S2 mini & DS18B20

Usermods
1

Hi to all.
I’m new to wled but know how to compile and stuff.

Lights work almost perfectly, sometimes need powercycle but otherwise perfect.
I had really bad flickering on esp8266 at colder weathers.

I have a problem with ESP32S2 and DS18B20, just can’t get it to work.
ESPHome worked just fine with same setup.

platformio_override.ini:

; Options
; -------
; USERMOD_DALLASTEMPERATURE                      - define this to have this user mod included wled00\usermods_list.cpp
; USERMOD_DALLASTEMPERATURE_CELSIUS              - define this to report temperatures in degrees celsius, otherwise fahrenheit will be reported
; USERMOD_DALLASTEMPERATURE_MEASUREMENT_INTERVAL - the number of milliseconds between measurements, defaults to 60 seconds
; USERMOD_DALLASTEMPERATURE_FIRST_MEASUREMENT_AT - the number of milliseconds after boot to take first measurement, defaults to 20 seconds

17 is temperature pin
16 is led pin
No resistor as I did not need it with ESPHome.

Screenshots
In last screenshot I’ve added a line to usermod_temperature.h to publish sensor type in MQTT.
( json[F(“sensor_type”)] = sensorFound; )

Thank you all.

Wled non è supportato da quel esp32 s2 mini. Devi usare un altro esp 32.

Sorry I don’t speak Spanish but I kinda know what you say.
ESP32S2 is not supported, I should use another type ESP32?

As i said, WLED is working perfectly fine (occasional hickups with wifi connection but nothing major).
Usermod is not working right or there is some library issue or something else.
I compiled firmware myself.

4

as i told you esp32 s2 mini is not compatible with wled. I don’t know how you managed to install it on s2 mini. :grinning: however if you use an esp 32 it works great :v: bye

You can look my platformio_override.ini, lolin_s2_mini :slight_smile:

I made order for C3:s, hopefully I’ll get temp sensor to work with C3.
Just curious if it is just a library issue.

Unable to debug as lights are outside and I have no way to serial monitor atm.

Check the “.pio/libdeps” folder for your custom build environment.

Not sure if you’re having the same issue, but I was having problems compiling the Temperature usermod for a D1 mini, and after some poking around found it wasn’t copying all the libraries to my new build environment.
I just copied the libraries over from another build and everything compiles OK now. Hopefully that gets it going for you too.
I’m hoping to get it going on a lolin s2 next as well :grinning: :crossed_fingers:

Thank you.
I kinda gave up on this and just waited C3’s to arrive.

I’ll look into this.
