Notifications - problem with internet connection
When server starts all devices are disconnected. It wouldn't make sense to always send notifications about all devices in that case. If you start server, you already know that you need to send SMS to all your TK102B devices. If there is an issue with network connection on the server side, you can set up a service to check it (e.g. https://uptimerobot.com/) and it will notify you.
I have problem with my TK102B device.
When the internet disappears on the SERVER SIDE (or server is off), after several minutes TK102B will switch off GPRS and will not go back to work. To re-enable it, I have to send sms: "adminip123456 <ServerIP> 5002".
But to know about it, I would have to check it often.
Is there a way to be notified?
When the server starts, it does not tell about disabled devices. Unfortunately the device must switch from ON to OFF to send mail.
