Hi All,
I tried to integrate HASS with soft PLC based on Codesys 3.5.
I would like to create interface in HASS for my automation system. I would like to use Modbus TCP/IP to send and receive data from PLC.
I managed to test modbus connection using “switch”, “sensor” form hass example .
I have problem with termostat for modbus communication. I am able to receive current temperature, current setpoint (in case of changeing register by e.g server) but I cannot send setpoint to my modbus server. My example is listed below.
climate:
- platform: modbus
scan_interval: 5
name: termostat salon
hub: hub1
slave: 1
data_type: uint //i’ve tried int - doesnt work
data_count: 1
scale: 1
offset: 0
precision: 1
max_temp: 30
min_temp: 15
temp_step: 1
target_temp_register: 15 // holding register 15
current_temp_register: 16 // holding register 16
Anyone has similiar issue?
