Modbus scan_interval: too slow option Serial RS485 Now with video


Posted here

I have modbus controller for my low power toggle switches in my house. But the 1 second option is just way too slow. Is it possible to make it scan down to ms instead. I have testet it in Node-red but the setup is difficult when more then one device is connected to the modbus. In node red it has no problem with scanning in 5ms. I want to make sure my 5*(32) modbus inputs are scanned every 50ms to make the toggle work correctly.
