Thanks all for support!

Now it works! I set GPIO 21 and 22 in the hardware menu. Then I set in the menu devices the gain to 1x. Now I took a poti at +3,3V and GND. The middle I connect to A0. The Value I got is between 0 (0V) to 26443 (3,3V). I have 2 more questions: To get in the Value the information 3,3, how could I rea...

OK, thanks I made it and it works with the DS18b20.

Now I will try again to use the ads1115.

But when I try to connect, which GPIO I should take?

Would there be any possibility to show my screen via team viewer to find out the problem?

I changed in the hardware tab also the setting of I2C : SDA - GPIO 21 and SCL - GPIO 22 but it does not work. Now I took a DS18B20 temperature sensor. I had a resistance (4,7k) between + and data. I changed the SDA to GIPO 4. Nothing after scanning :(. Do I have to change any thing in the setup, if ...

Ok, so I have to set down my 0-5V analog signal, that is no problem. No to the circuit. I go in the scan menu of ESPEasy, and let it scan. Result: No I2C devices found In the setting of I2C is SDA - GPIO 4 and SCL - GPIO 5 I connect like this: ads1115 VDD 3,3V esp32 GND GND SCL 22 SDA 21 Is there so...

Do I understand it right, in the data sheet VDD is up 7V. So couldn't I connect the ads on the 5V pin of the esp32?

Thank you very much for your information. I thought I could connect max 5V to the analog pin😳, so without your note I think I destroyed the ads. I connected the ads1115 to the 3,3V pin and ground of the esp32. The I2C signal I connect to pin 21 and pin 22. What for me is not clear how to manage this...

Hello, I have not many experience to use espeasy on an esp32, so I hope I could get here some information. I want to to measure a signal 0-5V and want to send it to my mqtt adapter in the ioBroker. So I bought an ads1115 to connect it with my esp32. But what is the right way and what do I have to se...

Hello venti, you describe that it is possible to flash an esp32 with esptool. I have a Lolin32 V1.0.0 board from Wemos. I tried to flash it with the ESP Easy Flasher, but it does not work. To find a solution I found this thread. My problem is, I do not know how to use esptool. Could you give me some...
