Prerequisite
To make this setting, you must have access to the user interface. If you don't, see here how to do it:
iRelays available To use iRelays, you need to buy one of this devices.
The iRelay can be used locally or as a transmitter to the cloud. It acts as a repeater and reports the received measurement results to a cloud service. For information on how to create a cloud service in the relay, please refer to the instructions for the relay.
In this manual, you will learn how to configure the relay and the Hydrom so that the measurement values are sent to the relay and can then be displayed locally.
If the iRelay is to be connected to the Internet or an existing network, the following steps must be done.
The device has no battery, so you have to power it with a USB-C cable.
Now open the Hydrom's user interface.
To access the menu bar, you need to click on the three lines in the upper left corner. (See arrow) Then the menu bar will open.
On the "Services" page, you have the option to select and configure various interfaces and cloud services for use with its system. On this page, users can choose from three different interfaces - HTTP, MQTT, and TCP - and several cloud services, and then enable and parameterize these options to fit their needs. This page is a useful tool for those who want to connect their system to the cloud or other external services and customize the way data is transmitted and received. With the options available on the Services page, users can customize their system to meet their specific needs and ensure that it can communicate effectively with other devices and systems.
On the "Service" page, the http-Server service must be activated.
Content:
Server Set the server to "192.168.4.1".
Port Set the port to "80".
URL Set the server to "/gravity".
The iRelay needs a special name for the hydrom like this: "1-Hydrom[SG]". You can find out how to change the name here:
In order for the hydrom to send the readings to the iRelay, the hydrom needs to be connected to the iRelay's WiFi.
SSID Set the SSID to "nautilis-ispindel".
Password Set the password to "1234567890".
You can find out how to change the Network Settings here:
To avoid using too much power, we would turn off Bluetooth when it is not needed. This was documented here:
In order for the hydrom to transmit data reliably, a DeepSleep time must be set. This is documented on this page:
Saving the data is important because it is the only way to connect to the service after waking up from DeepSleep.
You can check if the save was successful by looking at the settings file at http://hydrom001/settings.json/. This file is the persistent storage of the hydrom.
A second way to check the saving is to reload the page (all browsers offer this). If then the properties are reloaded, the hydrom has accepted them, otherwise the old settings are reloaded.
Enabling DeepSleep is mandatory for the hydrom to send data. If DeepSleep is activated, the hydrom wakes up after the specified time and sends the data to the set service. After that, the hydrom goes back to sleep and waits for the new service.
In order for the device to send readings to the service at the set interval as intended, the Hydrom must be put into deep sleep.
There are two ways to put the Hydrom into deep sleep.
The easiest way to put the Hydrom into deep sleep is to turn the power switch off and on.
The other way is to put the device into deep sleep using the user interface. To do this, open the navigation bar and go to the "DeepSleep" tab.
