I have not yet found my ADS1115 boards, so I can't do the testing for you to see whether it can be reproduced here. Thank you for your support. I think I'll have enough time spring next year, when the plants finished over-wintering. I'll try your suggestion to combine some resistors and simulate th...

Back again with quite a lot of data and measurements. No deep-sleep with short timings for readouts (same values) but switching timings for all sensors. You might see, when I've changed the timings. https://drive.google.com/file/d/1XX_IIAwOoaECsbgzMg-jJ_DEsw-ey7lm/view?usp=sharing No deep-sleep with...

Small update:
I've switched the d1 to deepsleep and readouts every 120 seconds. Now the diagramms are messed up. What have seemed to be kind of stable is now just horrible. I'd try to analyse if I can find any kind of pattern ...

A very simple test would be to add various resistor combinations to the inputs. e.g. GND --- 10k --- pin --- 33k ---- 3V3 And then different combinations per pin. This way the sampled values should always be the same +/- some noise. But still you would see if inputs are changed. I'm sorry, but I do...

Back from testing and I'm a little bit frustrated. Everything seems to work properly. Initially I've connected all the sensors to the board. Made the settings to get sensor 1 assigned to sensor 1, 2 to 2, etc. Made some tests. Disconnected all sensors and reconnected them to try if they will be reco...

Okay, I did several tests and something seemed to work. The diagramms are now stable and there seems to be no switching furthermore. I'd go on with testing and will be back and report if I figured out where the problem came from. Great. Have you used the 'diagramms' of ESPEasy (the Stats checkbox, ...

Are you using long cables between ESP and ADS chip? - no, the ads1115 is soldered to a tripple base and directly connected Are you using pull-up resistors between SDA and 3V3 and SCL and 3V3? And if so, what value? 10k is typically enough, but on longer cables, you may want to use 4k7. N.B. having ...

Thank you for your response. I've tried what happens if I experiment with the speeds of the I2C interface. Sadly I think it didn't the trick. I tried with standard settings (100 kHz) and also with lower speeds (50 kHz) but neither resulted in a better behavior of the readouts. But - maybe, it is sta...

Hello together, recently I started with some esp d1 boards and got esp easy to run well. A lot of things work properly (different sensors, communication to iobroker, etc.). Nonetheless I*m still at beginner level. So for now I took a d1 to measure the water of four plants. The ADS1115 is recognized ...
