Shelly Plug and Washing Machine Automation: Solving the 40-Minute Delay

I’ve been working on automating my washing machine using a Shelly Plug, and I want to share my experience and solution to a problem I encountered. This might be helpful for anyone else dealing with similar delays in their smart home setup.

The Setup:
I connected my washing machine to a Shelly Plug and set up a scene in my smart home system. The idea was simple: detect when the washing machine starts (based on power consumption) and trigger an activity. Initially, everything seemed to work fine—the power detection worked, and the activity was triggered. However, there was a significant issue: the notification about the washing machine starting came 40 minutes after the machine had actually turned on. That’s definitely not ideal!

The Problem:
I quickly realized that the delay was due to how the Shelly Plug detects power changes. The sensor wasn’t responding as fast as I needed it to. This meant that my automation wasn’t nearly as seamless as I had hoped.

The Solution:
After some research and experimentation, I found a way to reduce the delay significantly. Here’s what I did:

  1. Adjusting the Shelly Plug Settings:
    I tweaked the sensitivity settings on the Shelly Plug to make it respond more quickly to power changes. This involved lowering the threshold for what constitutes a significant power change, ensuring that even minor fluctuations are detected promptly.

  2. Optimizing the Automation Logic:
    I revised the automation rules to include a shorter delay between the power detection and the activity trigger. This helped ensure that the notification was sent almost immediately after the washing machine started.

  3. Testing and Fine-Tuning:
    I ran several tests to see how the system performed with the new settings. Each test brought the delay down, and after a few adjustments, the notification was only a minute or two behind the actual start of the washing machine.

The Outcome:
While I couldn’t eliminate the delay entirely, I managed to reduce it to a manageable level. This makes my washing machine automation much more practical and useful. It’s a small victory, but it’s one that makes my smart home setup feel that much more polished.

Tips for Others:
If you’re dealing with similar delays in your smart home setup, here are a few tips:

  • Check Sensor Sensitivity: Make sure your sensors are set to detect changes as quickly as possible without causing false positives.
  • Review Automation Rules: Sometimes, delays are caused by overly conservative automation logic. Be willing to experiment with different settings.
  • Test Thoroughly: Don’t be afraid to run multiple tests to see how your system performs. Each test can provide valuable insights into how to improve your setup.

I hope this helps anyone else who’s struggling with delays in their smart home automation. It’s all about finding the right balance between sensitivity and reliability!

Happy automating! :rocket:
