Device Type
Taylor hybrid inverter (MQTT)

---

Configuration steps

Prerequisite: the MQTT broker that publishes the Taylor topics is reachable by the controller (default ports 1883 or 8883 for TLS).

1. Find the site filter
   In your Taylor portal / documentation locate the topic prefix
   (e.g. site_123/…). Use this as Site filter.

2. (Optional) create a broker user
   Create a dedicated MQTT username / password — or leave empty if the broker is open.

3. Add the device in SmartgridOne

   • Integrations → Add device

   • Choose Taylor MQTT Hybrid Inverter Protocol

   • Fill in the fields:

     Field	Example / note
     Host : Port	mqtt.example.lan : 1883
     Site filter	site_123
     Battery nominal power [kW]	5 (optional)
     Solar nominal power [kW]	8 (optional)
     Capacity [kWh]	11 (optional)
     Grid / consumption meter topics	leave empty unless needed
     MQTT username	leave empty if broker is open

   After saving, the inverter and its children (battery, PV, meters) appear.

stateOfCharge_frac	Battery state-of-charge (0 – 1)	—

¹ Calculated by the driver when absolute kWh counters are unavailable.

Troubleshooting

• No measurements – ensure topic …/raw_data/latest returns JSON with soc and active_power_in.
• Command ignored – smart-grid mode must be on and the new set-point must differ by at least ±100 W from the previous one.
• Multiple Taylor sites – run one driver instance per Site filter to avoid topic collisions.
