Hello.
I have these telegrams from a modbus smart meter:
The one I’m aiming to obtain on my Home Assistant has the intex 0x79 (Active Power). On those samples its numerical value is zero at that moment.
I know that its data_type is a “double long unsigned” (4 bytes), as stated in the device docs:
But with this config, the sensor always get the state “unavailable”:
sensor:
- platform: modbus
scan_interval: 2
registers:
- name: "Active power"
hub: 1
slave: 1
# 0x79
register: 121
register_type: input
unit_of_measurement: 'W'
count: 2
reverse_order: false
scale: 1
offset: 0
precision: 1
# double long unsigned
data_type: uint
I have other modbus sensors for this slave device working flawlessly, such as voltage and current.
From the modbus sensor documentation, is possible to set a custom data_type and its structure. Can anyone help on this, please?
Thanks.
