RS485 Modbus SHT30 sensor setting - Jan_W - 03-29-2026 Hi, I have RS485 SHT30 sensors like below.  How should I configure and wire it to use as sensor in KCS v3? Should I use rs485 TR/TS option? This is not a Kincony sensor. RE: RS485 Modbus SHT30 sensor setting - admin - 03-30-2026 TS option only work with kincony TS product, different product have different protocols. RE: RS485 Modbus SHT30 sensor setting - Jan_W - 03-31-2026 Thank You. I’d like to suggest: Option 1 – Custom sensor support: Allow users to manually define Slave address, register number, function code and value multiplier in the Sensors section - so any standard SHT30 RS485 sensor works natively as Sensor. Option 2 – Protocol documentation: Publish the KinCony TS Modbus register map so users can reprogram third-party sensors to match the TS protocol. Modbus Pull (v3.24.2): Can the new “standard Modbus RTU V2 protocol handler” read data from a third-party RS485 sensor and publish it via MQTT to Home Assistant automatically? I think many users have third-party RS485 sensors - this would be a very useful addition. Thank you!
