iSpindel WiFi relay

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 Blynk mobile application where graphs, analytics, remote insight into the state of the fermenter and more are available. After version 6, it is possible to send hydrometer data to the following services: UbiDots, BrewSpy, Brewfather, Monitor.Beer. 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 2mm thick steel barrel and a 6mm 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 is powered by a 5V micro USB 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. From firmvare V5.8.1 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.

An additional option
Ambient thermometer can be installed if you want. 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).

Nautilis Relay is  also available on Ebay!

If it is no longer available on Ebay, contact us and we will let you know when it will be available again.

Don’t forget on the calibration formula!

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.

To set up the Blynk service, you need to:

1. Network name (watch out for your WiFi network – be case sensitive), 2. Network password 3. Select Blynk server, 4. TOKEN (Blynk token)
Unclaimed fields must be empty.

To set up the UbiDots service, you need:

1. Network name (watch out for your WiFi network – be case sensitive), 2. Network password (select your WiFi network password) 3. Select service type (check Ubidots), 4. TOKEN (your API token in your Ubidots STEM account)
Unclaimed fields must be empty.

To set up a Brewfather service, you must:

1. Network name (watch out for your WiFi network – be case sensitive), 2. Network password 3. Select service type (select Brewfather), 4. PATH / URI (enter your personal PATH / URI )
Unclaimed fields must be empty.

To set up a BrewSpy service, you need:

1. Network name (watch out for your WiFi network – be case sensitive), 2. Network password 3. Select service type (highlight BrewSpy), 4. TOKEN (your hydrometer token you use) Note code BrewSpy services can only use 1 hydrometer.
Unclaimed fields must be empty.

To set up the Monitor.Beer service, you need:

1. Network name (watch your WiFi network name – be case sensitive), 2. Network password 3. Select service type (check Monitor.Beer), 4. PATH / URI (enter your personal PATH) / URI / ispindel /? Your username).
Unclaimed fields must be empty.

– In iSpindel settings, the interval must be set to at least 900 s (15min).

-The first time you connect to a service the name of your hydrometer is saved to the server and only then you can use it in the application. In the service, the calibration formula you are using must be specifically pasted.

-Firmware Update Over-the-Air programming (OTA) is a wireless upgrade of the device firmware. Opening the menu will open you an upgrade page. You find the latest firmware on the device you connected to the website and upload the same to the system. when you get the notification Ok, the firmware has been successfully upgraded.

– Management (Selecting the number of available hydrometers, setting high and low alarms)

– Measured data

-Reboot – Opening this link will reboot the device.

I’ve made Nautilis iSpindel app. You are welcome to try it out!

To start using it:
1. Download Blynk App: http://j.mp/blynk_Android or http://j.mp/blynk_iOS
2. Touch the QR-code icon and point the camera to the code below
3. Enjoy in app!

To install all the features built into the firmware 6.1.5 requires 6400 Blynk power, then use the QR below. All options are available on the local website, so this option is optional.
