Nautilis iSpindel iRelay Plus – USB-C (Additional option: thermometer & pressure sensor)
iSpindel WiFi relay is a device used for signal amplification and connection of a digital hydrometer – iSpindel, processing of received data and further distribution according to fermentation monitoring applications. iRelay + is also compatible with HYDROM hydrometers. The data measured by the hydrometer is displayed on a large TFT display, can be viewed via the local relay website or sent to the other suported applications where graphs, analytics, remote insight into the state of the fermenter and more are available. Now is possible to send hydrometer data to the following services: UbiDots, BrewSpy, Brewfather, Monitor.Beer, Grainfather, Little Bock, Brewers Friend, BrewBench, MQTT, HTTP, HOME ASSISTANT. The last time the hydrometer data was read, as well as the density, temperature, battery voltage, signal strength, name of the hydrometer, are shown on the device screen and website. The signal strength of the iSpindel WiFi relay was tested by placing the hydrometer in a 2 mm thick steel barrel and a 6 mm lid without a rubber seal with a stainless steel clamp system, and placed the barrel in a closed freezer. And in such conditions, the signal easily broke through to the hydrometer.
Due to its extremely reliable connectivity, iSpindel consumes noticeably less power and thus lasts longer. iSpindel WiFi relay plus is powered by a 5V USB-C cell phone charger that can also be used to charge your hydrometer battery, and your power consumption is negligible. The iSpindel hydrometer no longer needs the Internet, and WiFi relay it doesn’t need either. Now the internet connection is only needed when you need a remote insight into the fermentation state via the previously mentioned applications. The gadget can greatly facilitate and speed up the calibration of the iSpindel hydrometer, as it displays an angle.
The relay firmware is constantly being upgraded and improved. Firmware upgrades, if necessary, they upgrade wirelessly via OTA (Over the Air) and the device’s web interface.
Currently 2 iSpindel hydrometers can be connected to the iSpindel WiFi relay. Any irregularities or warnings on the display are shown in red colour. A confirmation tone sounds when saving the settings and a continuous alarm occurs at too low or too high hydrometer temperature and when the specific gravity falls below the value you specify.
iSpindel relay+ has posibility of entering OG for 2 hydrometers from which % ABV and attenuation are then automatically recalculated. The latest firmware has SG and temperature correction for both iSpindels applied to the Display and Blynk Application.
The battery status of the iSpindel is displayed as a graphic icon showing the battery voltage and as a percentage of the remaining voltage. Next to the battery status icon is a graphic display of the signal strength according to the hydrometer, and next to it is a graphic display of the signal strength according to the home WiFi network. If the Relay is not connected to home WiFi then the “D” (Disconeconnected) mark is visible instead of the signal strength display.
If you use Plato degrees instead of SG, then you can change the density unit for each iSpindel in the settings.
If you accidentally calibrated the iSpindel in the Plato unit, you can convert P to SG in the management settings of relay local web site. This only applies to iRelay, while the application receives the original iSpindle data.
The device only works on 2.4ghz WiFi network.
Additional thermometer option
The outdoor or ambient thermometer has the ability to alarm you when temperature too high or too low is. The length of the sensor can be extended without affecting the measurement. Also, this thermometer can be placed on the fermenter shell and serve as protection against fermentation temperature controller failure (STC – 1000). In the thermometer settings, you can select the unit in degrees C or degrees F.
If the relay has a built-in temperature probe then you can add a BrewSpy new device, Brewfather Custom Stream device or Grainfather custom controller to display temperature on the BrewSpy, Brewfather or Grainfather app. Temperature appears in the interval of 1,5 or 15 minutes and is sent independently of the interval of the iSpindle.
Additional pressure sensor option
Nautilis iRelay + P receive data from a pressure sensor, shows it on the screen and forwards it to applications via a WiFi network. With the desired applications, you can monitor the desired values on your computer and mobile applications, depending on the type of application you are using. Currently supported applications are: BrewSpy (Send interval min 5min), SensorSpy (Send interval min 5min), Brewfather (Send interval min 15min). Depending on the application, in case of alarm values, they will be notified via a notification on the mobile phone.
The Nautilis iPressure device allows pressure units in Bar or PSI, and temperature in degrees C or F.
The device is usually not purchased with a pressure sensor, but it should be ordered separately. The order link is: Here
The pressure sensor has 3 wires, with iPressure you get a preparation where you have to connect these wires. You can extend the length of the pressure sensor cable as desired.
When purchasing the iRelay Plus please note that it is an option with included pressure sensor hardware and software –> iRelay +P. Irelay + without this option cannot have a pressure sensor, while every irelay +P can be iRelay+
How to use Nautilis iSpindel iRelay?

To set up the Home Assistant service, you need to:
Connecting a device to MQTT and integrating it with Home Assistant involves establishing communication between the device and the MQTT broker, and then configuring Home Assistant to automatically recognize and interact with the device. Here’s a simplified description without delving into the YAML configuration file:
Connecting Your Device to MQTT:
Set Up MQTT Broker: Start by configuring an MQTT broker, either locally (e.g., Mosquitto) or using a cloud-based service.
Device Configuration: Ensure your device supports MQTT and configure it to connect to the MQTT broker. Provide the necessary credentials such as the broker’s IP address, port, and authentication details.
Integrating with Home Assistant:
Install MQTT Integration: Within Home Assistant, install the MQTT integration to enable communication with devices using the MQTT protocol.
Auto-Discovery: Utilize Home Assistant’s MQTT Auto-Discovery feature. As the device publishes data to MQTT topics, Home Assistant automatically detects and configures corresponding entities (e.g., sensors, switches).
Device Appears in Home Assistant: After configuration, your device will appear in Home Assistant as entities representing different aspects of the device, such as temperature sensors or switches.
Customization (Optional): Home Assistant allows customization of entity names, icons, and other attributes. Customize the appearance of your device within Home Assistant based on your preferences.
By following these steps, your device seamlessly integrates into your Home Assistant setup. You can monitor its status, receive sensor data, and incorporate it into your home automation routines. The MQTT and Home Assistant combination offers flexibility for customization and control to suit your specific needs.

How to connect wires and pipes to a pressure sensor
With iPressure or iRelay supporting the pressure sensor, you will receive all the preparation in the device with wires that connect to the internal connector. You only need to connect 3 wires from the pressure sensor to them. The pressure sensor has wires in 3 colors: Black, Red, and most commonly Green. Connect the black sensor wire to the black device wire, the red sensor wire to the red device wire, and the green sensor wire to the yellow device wire. If you want to extend the sensor wire, you can also do so with any thin wire without affecting measurement accuracy. Finally, protect the wire with heat shrink tubing.
To connect pipes to the pressure sensor, you have several options: The simplest method is to purchase a Brass 1/8″ NPT Female to 5/8″ Inch OD Tube Pneumatic Air Fitting. Then, you only need an 8mm tube that connects to the Kegland Spunding Valve. If you don’t have the fitting, there is also a DIY method you can use. You can thread a 12mm tube onto the sensor and secure it with a hose clamp. Then, attach a reducer to the 12mm tube to match the size of the tube you are using.
