📦 Install a sensor kit

One click adds several sensors as separate slaves — like a real integrated multi-sensor product talking on RS-485.

What's in each kit?
Cold Storage Station 3 slaves
Combined T+RH probe + Door switch + Compressor energy — 3 slaves that together monitor a refrigerated room.
  • sensor_temp_humidity — Room T+RH
  • sensor_door — Door switch
  • sensor_energy_1ph — Compressor energy
Pump House 4 slaves
Flow + Pressure + Tank-level + Pump-energy — the four readings you need for a booster-pump skid.
  • sensor_flow — Outflow meter
  • sensor_pressure — Discharge pressure
  • sensor_level — Tank level
  • sensor_energy_1ph — Pump energy
HVAC Room 2 slaves
Combined T+RH probe + AC energy — minimum kit for office / server-room HVAC.
  • sensor_temp_humidity — Room T+RH
  • sensor_energy_1ph — AC energy
Greenhouse 3 slaves
Combined T+RH probe + Irrigation tank level + Vent — the basics for a horticulture demo.
  • sensor_temp_humidity — Air T+RH
  • sensor_level — Irrigation tank
  • sensor_door — Vent / door
Boiler House 4 slaves
Pressure + Temperature + Flow + Energy — process monitoring around a steam boiler.
  • sensor_pressure — Boiler pressure
  • sensor_temp — Steam temperature
  • sensor_flow — Steam flow
  • sensor_energy_1ph — Boiler energy
