Hello everyone, I wanted to share my recent experience with optimizing energy costs for my home appliances. I’ve been experimenting with a setup that uses sensors, MQTT, and dynamic pricing to save on energy bills. Here’s how I approached it:
-
Understanding the Problem: I noticed that my energy costs fluctuated significantly throughout the day. With a dynamically priced energy contract, I realized I could save money by running appliances during off-peak hours.
-
Setting Up Sensors: I installed power sensors on my washing machine, dishwasher, and tumble dryer. These sensors measure energy consumption in real-time and send data to my MQTT broker.
-
Using MQTT and InfluxDB: The sensor data is stored in InfluxDB, which allows me to analyze energy usage patterns over time. Grafana has been invaluable for visualizing these patterns and identifying optimal times to run appliances.
-
Dynamic Pricing Integration: I integrated my setup with Tibber, which provides real-time energy pricing data. Using a Lua script, I analyze the pricing data alongside my appliances’ energy profiles to determine the cheapest times to run them.
-
Automation: The script calculates the optimal start times for each appliance and triggers them automatically. For example, my dishwasher now runs during the early morning when energy prices are lowest.
-
Results: After implementing this setup, I’ve noticed a significant reduction in my energy costs. While the savings per appliance are modest, the cumulative effect across all my white goods has been impressive.
I’d love to hear your thoughts on this approach! Do you have any suggestions for improving the automation or adding more features? Let’s discuss!
