Is there a way to send raw hex like 01 03 00 00 00 12 C5 C7 to the modbus port in scripts?
And subsequently listen to the MODBUS port and take action when a specific value is received?
Scenarios :
- switch the light on (modbus relais) when a specific bluetooth device is in range.
- switch the fan on (modbus relais) to cool my routerboard once it gets too hot
- send a warning to a webhook if the temperature of my RS485 temperature sensor gets too high
