A8S and Modbus sensor - milan.net - 06-10-2024 Hello, I would like to ask for help setting up A8S with RS485 Temperature and Humidity Sensor Modbus RTU Use By SHT30 an ESPHome https://shop.kincony.com/products/rs485-temperature-and-humidity-sensor-modbus-rtu-use-by-sht30 Thank you RE: A8S and Modbus sensor - admin - 06-10-2024 i suggest you use SHT31 connect with A8S' i2c extender interface, it's easy for ESPHome. if you really want to use RS485 bus for long distance. ok, the product's link is ok.

Hello, i already have the rs-485 sensor and need to place it 70m cable length away. Can you please send me ESPHome example how to use the sensor? RE: A8S and Modbus sensor - admin - 06-10-2024 when have free time, we can have a test. RE: A8S and Modbus sensor - milan.net - 06-12-2024 Can you please send me some more information about the sensor? Default address? Used registers to read etc? RE: A8S and Modbus sensor - admin - 06-12-2024 the sensor default address is 1, RS485 9600bps read temperature and humidity data from 0x0 register, read 2 bytes. here is our arduino demo source code , maybe can help you. https://www.kincony.com/forum/showthread.php?tid=5702 RE: A8S and Modbus sensor - milan.net - 06-12-2024 Thank you RE: A8S and Modbus sensor - milan.net - 06-15-2024 Hello, If some one would be looking for the same thing, this is the part of yaml that works for me: modbus: id: modbus1 uart_id: mod_bus modbus_controller: - id: a8s address: 0x01 modbus_id: modbus1 setup_priority: -10 update_interval: 5s uart: id: mod_bus tx_pin: 33 rx_pin: 32 baud_rate: 9600 stop_bits: 1 parity: NONE sensor: - platform: modbus_controller modbus_controller_id: a8s name: "Box Temp" id: modbus_temp register_type: holding address: 0 unit_of_measurement: "°C" value_type: S_WORD accuracy_decimals: 1 filters: - lambda: return x / 10.0; - platform: modbus_controller modbus_controller_id: a8s name: "Box Hum" id: modbus_Hum register_type: holding address: 1 unit_of_measurement: "%" value_type: S_WORD accuracy_decimals: 1 filters: - lambda: return x / 10.0; RE: A8S and Modbus sensor - admin - 06-15-2024 good, thanks share your code. RE: A8S and Modbus sensor - martinvysnovsky - 07-26-2024 Hello I want to use several of these sensors in one bus. How can I change the sensor's address? In which registry the address is stored? Thank you |
