This program is intended to help manage Ethereum miners and help turn them off when ETH Gas prices are too low. When run, the package will make an API call to ETH Gas Station's API to get the current gas prices in GWEI. The program will record the result in a SQLite DB stored in the db directory locally and will calculate the Exponential Moving Average(EMA) over the last n calls and compare that to a threshold parameter to determine if the miner should be turned on/off. The EMA is used to avoid turning the miner on/off if there are sudden spikes in the price. It should only turn on/off based on the average price over a pre-determined timeframe. A GAS_PRICE_THRESHOLD parameter can be modified in main.py as well as a N_RECORDS parameter which controls how many previous API calls to compare against. This program is intended to be scheduled so that it runs every few minutes.
Lastly, the miner executable file and the corresponding .bat file should be placed in this directory or otherwise you can edit the PROCESS_NAME and BAT_FILEPATH variables in the miner.py file to point to the right path where those are installed.
A free API key for ETH Gas Station is needed to run this program and should be exported as an environment varialbe named ETH_GAS_STATION_API_KEY.
Install:
pip install setup.pyRun manually:
python main.pyNote: This is intended to run on a scheduled basis
