Instructions for use
For Zephyr owners receiving their equipment
1. Where to install your Zephyr sensor
First of all, make sure that your WiFi connection is working properly and that it's available where you want to install your sensor. You can use your cell phone to check the quality of your WiFi reception, depending on the position of your box in your home. The ideal location is facing the prevailing winds in the direction of a source of pollutant emissions to be monitored (but not sheltered from the winds), at a height of 2 or 3 meters, away from known sources of pollutants (barbecue, parking lot, chimney, etc.). The instrument is fitted with a mounting bracket so it can be placed on a mast, a facade, etc. In its final location, plug the Zephyr into a mains socket using a smartphone charger and a USB C cable. Flat cables can easily pass between window joints.
2. Configuring your sensor
Your Zephyr sensor has a unique identifier (SEN55-<SENSOR_ID> or SCD30-<SENSOR_ID> ) which will be supplied to you on receipt.
Example of sensor ID: SEN55-050
The first thing to do is to configure your Zephyr sensor with the parameters of your Wifi network, its name (SSID) and password. To do this, connect your Zephyr sensor close to your box. This is done using a USB A / USB C cable and a phone charger plugged into the mains, or temporarily into a computer. Then, using your phone, tablet or computer, search for the "AutoConnectAP" network and connect. Once connected, open a web browser and go to http://192.168.4.1 . On many phones and tablets, you'll be directed there automatically. (See below)
Select the network you wish to connect to. Its name will be automatically entered in the SSID text box (SSID = name of your WiFi network). In the example above, two networks are available, with the SSIDs "My wifi network" & "TEST". Use the other box, Password, to enter the chosen network password, then press the Save button. Disconnect then reconnect the sensor (to the plug or charger is easier than on the Zephyr itself).
Your Zephyr sensor will now abandon its "AutoConnectAP" network and connect to your WiFi network. It will send its first set of data to the server within 2 to 5 minutes. To check this, connect to the Zephyr sensor network server (ask your project managers).
If this doesn't work, disconnect your Zephyr sensor, then reconnect it and repeat the configuration. If everything works, install your Zephyr sensor in its final position. Reconnect it and check again that data is being sent to the server.
Remarks :
If you wish to change your WiFi network password. Disconnect your Zephyr sensor, change your password, reconnect your Zephyr sensor and repeat the configuration. If you want to change the name of your WiFi network, you'll need to completely reset your Zephyr sensor.
3. Known faults
In the event of a power failure, the Zephyr will shut down, as will the box. When the power is restored, the Zephyr will try to connect to the wifi network, but the box will not yet be operational. The Zephyr will not be able to connect to it. In this case, as soon as the wifi is operational, disconnect and reconnect the Zephyr so that it can reconnect.
