I set up a Raspberry pi to monitor my keg fridge. Every 10 minutes a python program gets pressure (using a sensor, ADS1115, and level shifter), temperature (using DHT22 sensors), and keg weight (using a wheatstone bridge load cell array and an HX711 amplifier). The data is sent to my Android phone (using Tasker and AutoRemote) where I get data displayed on my phone's home screen. Data that is out of expected range (low pressure, high temperature, or low keg quantity) creates a notification on my phone. Tasker then sends this data to a Google Sheet for logging. The screenshot with the rectangles, look at the brown one near the top left, and the one next to it. Keg fridge and fermenters (which are updated every 15 minutes). The screen with the keg is a Tasker scene and is a depiction of keg quantity. Turns yellow then red as volume depletes.
