kc868 pzem017 18b20 - billythekid57 - 10-26-2025
Hello to the forum, this is my first post. I purchased two KC868 A16 boards to use with DS18B20 temperature sensors and PZEM 017 meters. I saw two firmwares here; one has working inputs and outputs, but it doesn't have DS18B20 or PZEM listed. I tried the other for DS18B20, and it works, except now the inputs are missing. I tried using TasmoCompiler to create a binary, but the update says the file is invalid. I set ESP32 and ESP32 S3, but neither works. If anyone has a firmware that works, please let me know.

Thanks

if use by KCS firmware, not support PZEM. if you want use them together, suggest you config by ESPHome.

I wanted to use Tasmota, which uses rules to start the fans automatically. With the DS18x20 firmware, both the DS18B20 and PZEM017 work. The only thing missing are the inputs, which aren't needed for now. I'd like to know how to set this ESP32Wroom32... C2, or C3, or S3, or how?

make sure your tasmota firmware have compiled with PCF8574 i2c chip function.
