Summary
HA-NILM, a local Non-Intrusive Load Monitoring system for Home Assistant that estimates individual appliance usage from whole-home power data, has released version 1.1.9 with support for multiple mains power sensors. The update makes the system compatible with split phase, three phase, multiple meter, and independently monitored panel setups, allowing each appliance model to be assigned to the specific mains sensor that powers it for training and inference. Users can view each mains sensor individually or combine them into a single "All Mains" view, and the mains association selected during training is stored with the appliance model for use in previews and live inference. The release is backward compatible, automatically migrating existing single mains installations without requiring retraining.
Hey everyone, For anyone discovering it for the first time, HA-NILM is a local Non-Intrusive Load Monitoring system for Home Assistant. It uses your whole-home power data and a short training process to estimate when individual appliances are running and how much energy they use. I’ve just released HA NILM 1.1.9 , with support for multiple mains sensors. What’s new Multiple mains sensors You can now configure multiple mains power sensors, making HA-NILM suitable for split phase, three phase, multiple meters, and independently monitored panel setups. Each appliance model can be assigned to the mains sensor that actually powers it, and inference is performed using that specific feed. All Mains view You can view each mains individually or combine them into a single All Mains view. Mains aware training When training an appliance, you select which mains sensor it belongs to. That association is stored with the model and used automatically for previews and live inference. Backward compatible Existing single mains installations are migrated automatically, with no retraining required.
