Been following this thread for a while - really solid VPD and climate automation setups in here. One thing I kept noticing is that most builds handle the environment side well but nothing is looking at the plants themselves. You can have VPD dialed to the tenth of a kPa and still miss a calcium deficiency because no sensor is checking what the leaves actually look like.
Just shipped a custom integration for this: GitHub - plantlab-ai/home-assistant-plantlab: PlantLab automation for Home Assistant · GitHub
Service action (plantlab.diagnose) takes a camera entity or image path and returns structured JSON - specific condition, confidence score, growth stage. 30 classifiable issues including individual nutrient deficiencies and pests. Works with Frigate or any camera entity.
The output is structured specifically so your automations can act on it. Light burn detected? Dim the light. Deficiency? Adjust the feed. The same way you’d respond to a VPD reading being off, except the input is a photo instead of a sensor value.
