Set up your data logger with your phone

What you do and what you see
The same five steps as in the animation, with the buttons named as they are on screen.
- 1
Create a pairing key first
Sign in to FairGrow. Click Sensors at the top and choose Add FairGrow data logger. Under Link without e-mail, click Create pairing key. You see a code of eight characters. Do this first: once your phone is connected to the data logger, you have no internet. Leave the window open.

Switch on the data logger
Connect the power. A new data logger first looks for a WiFi network it knows. There is none yet, so it creates its own network. It is called FairGrow-setup- followed by six characters, for example
FairGrow-setup-3A9F1C. - 3
Connect your phone to that network
Open the WiFi settings on your phone and choose the FairGrow-setup network. There is no password. Your phone may say there is no internet. That is expected. The setup screen usually opens by itself. If it does not, open your browser and go to
192.168.4.1. - 4
Fill in the setup screen
Choose your WiFi from the list, or type its name under or type the network name manually. Enter the password. Under Device name you can pick a name if you like, such as Greenhouse north. Type the pairing key under Pairing key and tap Configure WiFi. You see Saved. The data logger restarts and joins your WiFi.

Go back to your own WiFi and watch
Your phone usually switches back to your own WiFi by itself. The window on the platform waits for your data logger and shows three check marks: Data logger reported in, Linked to your account and Online and reporting. At the last one your dashboard opens by itself.
No Pairing key field on the screen?
Then enter the e-mail address you use to sign in to FairGrow. As soon as the data logger is online, we e-mail you a pairing code. Enter it under Add FairGrow data logger. If that window is already open, you will often see a Link to my account button right away, and you do not need to type the code.
Six things that can happen
Most problems sort themselves out, or take one action to fix.
Wrong password
After about a minute and a half the data logger opens its setup screen again. Connect to FairGrow-setup again and have another go. Watch out for capital letters.
The setup screen does not open
Go to 192.168.4.1 in your browser. If that does not help, turn off mobile data for a moment, so your phone does not try over 4G or 5G.
No connection to FairGrow
You see this message when you try to create a key while you are still on the FairGrow-setup network. Switch back to your normal WiFi first.
Key expired or already used
A key is valid for an hour at most and works once. The window shows how many minutes are left. Just create a new one when it runs out.
My WiFi is not in the list
The data logger only sees 2.4 GHz WiFi. Tap Scan networks again or type the name yourself. Which settings work best is explained in connecting a sensor to your WiFi.
You were away for a while
A new data logger keeps its setup screen open for half an hour. Then it restarts and opens the screen again. So you can simply carry on later.
Only the data logger needs WiFi
You only set up the data logger this way. The satellites in the field have no WiFi. They send their readings to the data logger, and you do not have to do anything for that. Read more in ESP-NOW sensors.
If you use a Zigbee coordinator, linking works differently. See connect your own Zigbee coordinator.
Questions about setup
Do I need an app?
No. Everything happens in the browser on your phone or laptop.
Why do I have to create the key first?
Once your phone is connected to the data logger’s network, you have no internet. Then you cannot reach the platform to create a key.
How long is a pairing key valid?
An hour at most, and it works once. The window on the platform shows how many minutes you have left.
Can I use a laptop instead?
Yes. Any device with WiFi and a browser works.
What is 192.168.4.1?
That is the fixed address of the setup screen. It only works while you are connected to the FairGrow-setup network.
I have a new router. Do I need to link it again?
No. The data logger can no longer find its old WiFi, keeps trying for a while and then opens the setup screen by itself. Enter your new WiFi. It stays linked to your account.
