Hello,
i want to write a Modbus Register using the Modbus Integration. The datatype is 32int. I can read the register with the following sensor settings:
input_type: holding
count: 2
data_type: int32
The value i want to change is in the second register as far as i assume.
There is no Problem in writing to Registers with 2 bytes. How do i have to write the value?
Thx
Thanks. I know how to use that service. I already used it to write a single register (2byte, datatype int16), which works perfectly. But it doesn’t work when i am trying to write a 4 byte register with datatype int32.
Adress, variable, read or write, Data format, Data model.
No One an idea?
This is how iset the local time on my inverter using modbus. It’s a uint32 value:
alias: Sync klok Inverter1
trigger:
- platform: time
at: "14:00:00"
action:
- service: modbus.write_register
data:
hub: modbusdevice
unit: 2
address: 40000
data_template:
value:
- >-
{{ ((as_timestamp(now()) + 7200) | round(0) | float / 65536) |
round(0, "floor") | int }}
- >-
{{ ((as_timestamp(now()) + 7200) | round(0) - ((as_timestamp(now()) +
7200) | round(0) | float / 65536) | round(0, "floor") * 65536) | int
}}
mode: single
