Satec Powermeter

Satec worker supports PM180 power meters via Modbus TCP.

Install the Satec Powermeter

1. Clone the Repository

Use the same working directory for all the workers.

Inside your working directory, run the following command to clone the (miningos-wrk-powermeter-satec) repository:

git clone https://github.com/tetherto/miningos-wrk-powermeter-satec.git

After cloning the repository, move into its directory:

cd miningos-wrk-powermeter-satec

2. Install Dependencies

Inside the miningos-wrk-powermeter-satec directory, run the following command to install dependencies using npm:

npm ci

3. Generate Configuration Files

Next, run the following script to scan the config/ directory, copy each .example file into an active configuration file by removing the .example suffix.

sh setup-config.sh

4. Configure the Worker

After generating the configuration files, edit the files in the config/ directory to match your environment:

• common.json - Worker-wide settings including worker identity

• base.thing.json - Device-specific configuration for your Satec powermeters

Ensure your powermeter IP addresses and Modbus TCP ports are correctly configured and accessible from the worker machine.

5. Enable Debugging and Start the Worker

You can now start the worker by running the following command:

# PM180
DEBUG="miningos:*" pm2 -s start worker.js --name 'pm180-1' -- --wtype wrk-powermeter-rack-pm180 --env development --rack rack-1

6. Start Mock Server (Development Only)

For development and testing without physical powermeters, use the mock server to simulate a Satec device:

# Start mock PM180 powermeter
DEBUG="miningos:*" pm2 -s start mock/server.js --name 'mock-pm180-1' -- --type pm180 --env development --port 4027

Mock servers are useful for testing the worker without connecting to actual powermeter hardware.
