Help me choose where to start
Where to start
Home Assistant, MQTT, and ESP32 provide flexible integrations. Keep the system understandable by separating data transport, dashboards, control rules, and physical equipment protection.
Separate triggers from conditions and bound every action before enabling automatic watering.
Keep identifiers stable and configure availability and meaningful entity names.
Keep local automations in place and forward only the required states and commands to GrowerHub.
Choose your first step
| Situation | Where to start | Why |
|---|---|---|
| Home Assistant already controls equipment | Inventory entities and overlapping rules | One actuator should not be controlled by two independent automations. |
| You have a DIY ESP32 sensor | Calibration, availability, and a stable MQTT topic | Discovery improves setup but cannot correct a noisy measurement. |
| You want GrowerHub without replacing local MQTT | The directed connector | Local Home Assistant keeps working while the platform receives only required data. |
Add GrowerHub to your existing system
Keep local Zigbee2MQTT and Home Assistant, connect the devices you need, and organize zones without migrating every plant or scenario at once.
