Here’s what I have: ESP32 with the following register_type (Required): type of the modbus register. Also if I remove the modbus configuration from the yaml nothing is happening on the uart. My question is: Do you think that Home Assistant, with one e-Box-WiFi-01, connected to six EPEVER Tracer 1206-AN solar charge controllers via Modbus RS-485 daisy chain, can monitor and control each of the six connected 1206-ANs?

I am lost here I have only found 1 having a similar problem, but there was no solution to it or at least it wasn’t ### The problem Hi all, I'm new in ESPhome, please be patient with me :-) I have an issue in Modbus Switch behaviour: I have a 16 inputs & 16 outputs modbus board, I configured the code with 16 Modbus Binary Sensors (perfectly working) and 16 Modbus Switches reading and writing on a 16 bit holding register (0x70). And at my update interval rate I get: [D][modbus_controller:032]: Modbus command to device=1 register=0x104 countdown=0 no response received - removed from send queue. EBYTE NT1. I try to set the Register 0x18 (24) to 1. Modbus controller class. . I’ve created a branch of the standard esphome modbus / modbus_controller modules which adds a “disable_send” feature. Added yaml to basic. Extract bits from value and shift right according to the bitmask if the bitmask is 0x00F0 we want the values frrom bit 5 - 8. kincony. I have a weird and annoying problem with following number component of the modbus_controller: number: - platform: modbus_controller modbus_controller_id: modbus_dantherm name: "Set Temperature" id: temp_set device_class: temperature Inheritance diagram for esphome::modbus_controller::ModbusNumber: Public Types: using transform_func_t = std::function< optional< float >(ModbusNumber *, float, const If the device is running ESPHome 2021. 18 using esphome API INFO Successfully connected to hoszivattyu @ 192. Here it is again with the full code I have now after several updates to ESPHOME. com/item/1005003882507376. Some things I have noticed and tried The moment I disconnect the tx pin everything stops.
