How to use Nautilis iRelay?

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, 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.

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); save these settings and go back – then a new field appears in which you enter the rest data, 4. TOKEN (your API token in your Ubidots STEM account)
Please change your iSpindel name so that it only includes letters, numbers, periods, hyphens or underscores. [] in the name is unaccepted for Ubidots.

Ubidots new device to send the temperature of the thermometer from the relay: The Ubidots service must be marked and stored on the relay. Then a new field appears in the relay settings: Custom Stream URI/TOKEN in which you need to paste the Ubidots Token. Select the sending interval in the Thermometer menu.

To set up a Brewfather service, you must:

BrewSpy service can use multiple hydrometers.  The limitation is relate; save these settings and go back – then a new field appears in which you enter the rest datad to iRelay. So 1 iRelay can send data for 2 iSpindels. All you need is to check Share iSpindel token in Brewspy settings menu & Nautilis relay will do the rest.

BrewSpy Custom Stream to send the temperature of the thermometer from the relay: The BrewSpy service must be marked and stored on the relay. Then a new field appears in the relay settings: Custom Stream URI in which you need to paste the BrewSpy token from setup menu.

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.

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.
Sending interval is minimum 10 seconds

To set up the HTTP service (for example: Fermentrack), you need to:

1. Network name (watch out for your WiFi network – be case sensitive), 2. Network password 3. Select HTTP service, save these settings and go back – then a new field appears in which you enter the rest data 4. TOKEN, 5. HTTP server, 6. URI
The Port is hard-coded to 80.
Temperature sending interval is minimum 10 seconds.
Click the SUBMIT button and reboot the device.
