This branch contains modified versions of modbus and modbus_controller which includes an option to disable sending:
modbus_controller:
- id: myid
address: 0x0001
modbus_id: modbus1
update_interval: 10s
setup_priority: -10
command_throttle: 0ms
disable_send: True
The components can be used by using the external_components feature in your yaml:
external_components:
- source:
type: git
url: https://github.com/pcr20/esphome
ref: dev
components: [ modbus, modbus_controller ]
refresh: 2minutes
The data is retrieved by creating a sensor - use a lambda to access the data:
sensor:
- platform: modbus_controller
modbus_controller_id: orno_we_504
name: alldata
id: alldata_id
# 0x1 : modbus device address
# 0x3 : modbus function code (read holding)
# 0x00 : high byte of modbus register address
# 0x00: low byte of modbus register address
# 0x00: high byte of total number of registers requested
# 0x11: low byte of total number of registers requested
custom_command: [ 0x1, 0x3, 0x00, 0x00,0x00, 0x11]
lambda: |-
