I have 4 iSmartGate devices at home - 3 for garage doors and 1 for an entrance gate. I happened to be running Wireshark on my MacBook and I was pretty horrified when I saw a lot of constant traffic on these devices. Each sends a UDP packet to the IP address 255.255.255.255 (so it broadcasts on every device in my network), port 8005, every 2/10 / second. So, there are 20 UDP packets for each of my over 80 network devices every second! iPhones, iPads, wifi bulbs with humility, everything. I highlighted this with their support and I managed to reach the development team. Their answer was: ———————————— The ismartgate device is not a standard IoT device. Usually, IoT devices need the internet to work, but ismartgate does not need it because the server is embedded inside it. Ismartgate doesn't need a cloud to work, let me explain. Ordinary "connections" for a standard IoT work like this: IoT <———> INTERNET <———> Phone, but in the case of ismartgate, you can connect to it in two ways: ismartgate <———> cornfield < ———> Smart phone <———> INTERNET <———> Phone When you detect that your smartphone is on your local network, it will connect directly without using our relay cloud. All your data is always on your device. Once you open the ismartgate access application to detect if ismartgate is on the same network, the ismartgate application waits a few ms reading the UDP port to receive data from ismartgate. If it detects data, it will create a local connection, instead of connecting to the internet to connect to your ismartgate device. This is why you notice a lot of UDP broadcast data, because every ismartgate always sends a UDP saying, "I'm here." ———————————— Just I think this is crazy? I suggested that if they need to use transmissions, maybe their app might send a transmission when it activates ("Are you there?"), And the devices listen and respond accordingly, but no response from the developers, and support only says not a high priority! I would be happy to reinforce the thoughts of others about this and try to put some pressure on them to change this behavior. Unless everyone thinks I'm paranoid about all this unnecessary traffic to all the devices on a network (which could have a possible impact even on things like battery life on phones, etc.). We are waiting with breath ...
