Hi everyone, I wanted to share my recent experience with integrating an electric vehicle (EV) charging column into my Home Assistant setup. While the integration itself was successful, I encountered an unexpected issue with energy spikes during charging, which I found quite puzzling.
I started by setting up a custom sensor using the column’s exposed REST API to monitor instantaneous power consumption. To handle occasional internet outages, I created a secondary sensor that mitigates data gaps. The integration platform then calculates the energy consumed during charging and displays it on my energy dashboard.
However, every time I initiate a charge, the energy dashboard shows a sudden, unrealistic spike in consumption. This anomaly isn’t reflected in the actual power draw, as the REST API readings remain stable. The spike affects all related energy sensors, which aggregate consumption data across different lines in my home.
I’ve tried several approaches to debug this issue, including reviewing my sensor configurations and integration logic. I suspect the problem might be related to how the integration handles the initial data points when a charge starts. I’m considering implementing a delay or smoothing algorithm to filter out these spikes.
This experience has taught me the importance of thorough testing and the value of community support when troubleshooting complex setups. If anyone has encountered similar issues or has suggestions, I’d love to hear your insights!
