If you notice that data are missing or no measurements are being recorded, this is likely due to the Telraam device losing connection with your wifi. This article will explore ways to reconnect and try to avoid this in future:
1️⃣ ❓Is there a problem with the strength of your wifi signal?
If you experience such wifi outages regularly, there may be a problem with the strength of your wifi and the ability of your Telraam to connect to it. There are several ways to test this that will depend on your circumstances - for some tips, search for articles like this: https://www.howtogeek.com/426642/how-to-check-your-wi-fi-signal-strength/
If signal strength appears to be the issue, there are several options:
Move your wifi router closer to the window where your Telraam is placed.
Place your Telraam on another suitable window, closer to your router.
Consider purchasing a powerline or a wifi range extender (Telraam cannot help with internet connection or wifi signal issues, unfortunately).
2️⃣ ❓ Are there multiple frequency bands available (2.4 GHz and/or 5 GHz) on your router?
Raspberry Pi works better with 2.4 GHz. Try to connect Telraam to the 2.4 GHz frequency band. Different suppliers have different ways of dealing with this, so please contact your internet provider to find out how to proceed in order to select the 2.4 GHz.
Most modems transmit both frequency bands, then you can manually choose for each device whether you want it on the 2.4 GHz or 5.0 GHz network.
You may have an Internet modem that shows only one network name (=Service Set IDentifier=SSID). This 'smart' modem chooses for you on which frequency (2.4 or 5.0 GHz) it connects the devices, but does not know that Telraam does not work properly on 5.0 GHz. If you want your Telraam to work stably, you will have to disable this 'smart' feature and so you can manually select the 2.4 GHz network when connecting your Telraam to the Internet.

3️⃣ ❓ Does your wifi network consist of several access points? Do all access points have the same name?
When you select a wifi network on my.telraam.net during setup, only one wifi network can be chosen by name (like on your mobile device or laptop). If the access points all have the same name, you may not end up selecting the strongest access point for your Telraam.
To address this issue, try making the name of each access point unique so when reconnecting your Telraam you can select the best access.
4️⃣ ❓ Have you changed your wifi set up or password?
If you have new credentials to connect to your wifi,you will need to reconnect your Telraam in order to start counting again. Since the data being gathered must be sent to our server, it is essential to update your credentials.

When entering the details of your new wifi network and password, be careful not to make any typing errors.
5️⃣ ❗️ My wifi is down. How long will the data be stored for?
If your wifi is down see reports on the counting will be interrupted. However, the Telraam has a limited buffer. This means that some data from your Telraam will be stored and transferred to the server when your wifi is restored but may not appear on your dashboard.
The Telraam has a one-day buffer. If the wifi goes down, so the device is unable to upload its data to the server, this will be kept up to [midnight / the same day]. This means that if the wifi connection is restored (or there is connection in some other way) the same day, the count data will still be transmitted.
However, the dashboard on the website calculates and displays data for each hour. If no data is received in that hour, a gap will appear in the reports on the dashboard even if
