Scripts for bitcoin mining

See Antminer folder for script to put Antminer API into privileged access.

Use uploadhash.py to upload hash rate and miner temps to mydevices.com Cayenne dashboard. This will make the miner stats available on mobile device or web interface where you can get alerts (email or text) when your miner is in trouble.

Requirements

• Any computer that can run Python version 2 or Python version 3
• A miner like the Antminer S9 that supports the cgminer api.

Steps

The following setup steps are for Linux variants. For Windows PC the steps are analagous. For example, on Raspberry Pi use the sudo command. For Windows PC run command line as Administrator and set a path to your python folder. You get the idea. For Python version 2 use uploadhash.py and minerapi.py. For Python version 3 use uplaodhash3 and minerapi3.py.

1. Make sure python is set up on your computer. If you have problems then make sure you install dependencies and research the error message on Google.

 sudo apt-get install build-essential python-dev python-openssl
 sudo python setup.py install

2. install mqtt lib. This is a client to communicate with mydevices.com Cayenne back end.

sudo pip install paho-mqtt

3. Create your dashboard by signing up at https://mydevices.com/ and following the prompts. If you have any issues with the mydevices.com or Cayenne setup then get help on their community forum. Add a device through their site to generate a user id, password id, and client id that you will use in step 5. This will allow you to authenticate to their back end.

4. Download https://github.com/ckolivas/cgminer/blob/master/api-example.py (or just get it from this repository) Save it in any folder on your computer and rename it minerapi.py IMPORTANT! Make one small edit to the file. Comment out the following line by putting a # at the beginning of the line.

#response = json.loads(response)

The reason is that we want the raw json string coming from the miner as output, not the python object.

5. Put the file uploadhash.py in the same directory as minerapi.py and then customize with your settings. Edit the script uploadhash.py with the following info:

• ip address of your miner
• mydevices.com Cayenne user, password, and client id from step 2. IMPORTANT! You get this info from the Cayenne dashboard. These values are different than your login and password on that site.
• modify the polling interval if you so choose.

6. Now run the script, "python uploadhash.py". You can add the script as a cron task by using crontab -e and set it up to run @reboot. Google for instructions if you dont know how. If the script is running correctly then you will see the diagnostics output on the console with your miner stats, hashrate and temp.

user@raspberrypi:~/mydevices $ python uploadhash.py
13639.64 3 60 55 59
13622.19 3 60 55 60
13634.74 3 61 56 61

7. Check your Cayenne dashboard and configure your widgets. Don't forget to set up Cayenne Alerts from your dashboard to get notified when hashrate falls or temps rise.

The Antminer API is the same as cgminer api. See https://github.com/ckolivas/cgminer/blob/master/API-README
