iSpindel WiFi relay+ (iRelay Plus – USB-C) Additional 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. 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, Blynk IOT, MQTT, HTTP. 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
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 iRelay +P
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+ 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 WiFi Relay?
To turn on, use a Micro USB mobile phone charger that is declared exactly at 5V and a minimum of 700mA.
First change settings on the Ispindel management
Turn on your Ispindel and change the Configuration parts in the WiFi manager to:
SSID: nautilis-ispindel (If you have changed the AP SSID then enter the changed ssid here.)
PASS: nautilis-ispindel ssid password (If you have changed the AP Password then enter the changed pass here. The relay comes with a piece of paper with your password written on it.)
iSpindel name: 1-enter_your_name[SG] //The first character of the name must be a number; for Brewfather add [SG] on the end, without spaces. A maximum of 16 characters may be in the name of iSpindel. Some special characters take up more space, so make that number smaller. If the name is too large, there is a possibility of periodic resetting of the device.
Service Type: HTTP
Token: leave blank! // If there is a space here, the device will not connect.
Server address: 192.168.4.1
Server port: 80
Path/URI: /gravity
Don’t forget on the calibration formula! Use the SG calibration table located at this link.
If you use 2 iSpindels:
All settings are the same as on the first iSpindel, except that the name of the second iSpindel must start with the number 2:
iSpindel name: 2-enter_your_name-[SG] // first digit and then name and finally [SG] for brewfather
Nautilis Controller management system
View and edit relay settings (no internet required)
To view and change the device settings, first connect to the WiFi network that the device transmits, which is usually: nautilis-ispindel. After connecting to the network, some devices automatically open the Internet browser, and some require you to open the Internet browser and go to the address: 192.168.4.1
After that, the Nautilis Controller managment home page opens where you can view and edit the following settings:
-Configuration (configuration of your WiFi network,Blynk and other services)
Leaving one of the fields blank will save it as blank. The current settings view is at the bottom of the page. After saving, the device needs to be physically restarted, or you can use the Nautilis Controller management and the Reboot menu to make the changes active.
AP SSID & PASSWORD
As of firmware version 6.3.1, it is possible to update and change the AP SSID and password. This means that if you change it you have to change it on the iSpindel settings as well. Now the WiFi network transmitted by the relay can have the name of your choice. Do not use special characters, spaces, or more than 16 characters in the network name. When using 2 or more relays, the WiFi network names must be different between them.
