Attached one wire DS18B20 to sonoff th10. Flashed it and programmed it with arduino ide. Outside in the water the sensor provides error -127 random. I can filter out but wonder if some one has a clue because it only happens outside and the sensor in the water. Can it be a ground error? The sonoff is not grounded. The pond water is. Can this lead to crc errors in the sensor? Or can power outside parasites from the sonoff esp be to low or is wifi pulling more voltage down when sending the data? Please let me know if you have a clue.
