iRelay Premium Plus

The Nautilis iRelay Premium Plus is an advanced device designed to receive, process, and distribute data from digital hydrometers iSpindel and HYDROM. It ensures reliable fermentation tracking by displaying data on a 2″ round TFT screen, accessing it via the local web interface, or forwarding it to supported applications.

Supported fermentation monitoring platforms:

✅ MQTT / Home Assistant
✅ BrewSpy
✅ Brewfather
✅ Monitor.Beer
✅ Grainfather
✅ Little Bock
✅ Brewers Friend
✅ BrewBench
✅ UbiDots
✅ HTTP 

Exceptional WiFi connectivity

✅ Tested in extreme conditions:
The hydrometer was placed inside a 2 mm thick stainless steel fermenter with a 6 mm thick lid and locked in a freezer. The signal still penetrated easily.

✅ Energy efficiency:
Due to its reliable connection, iSpindel consumes less battery, significantly extending its lifespan.

✅ Internet-independent operation:

• iSpindel no longer requires the internet to send data to iRelay.
• iRelay also does not need the internet unless remote monitoring is required via one of the supported apps.
