Re: Speed control using PWM

The PWM functionalit on the WattmonPRO is not ready yet. Instead, you can use the IP1 module along with the WattmonPRO which allows you to set a PWM Output frequency and duty cycle. This in turn can power an SSR or mosfet with capacitor to create a 0-10v output to co tell the fan speed.

Custom Modbus RTU Commands

The Wattmon device type driver can handle most common modbus RTU interfaces, but sometimes it is necessary to communicate with custom commands, such as is the case with Delta RPI inverters that share a common address space and use a flag to set what the registers mean.
