Our units are collecting data through an ethernet connection, and submitting data wirelessly. This will be both the information to us about how the unit itself is performing, and the information to our customers on how their system is doing. The devices are also updated to the latest software versions remotely.
Here is some information about what services we talk to and network traffic we use.
For details about what Modio stores, see our Data retention Policy
Remote Services our devices communicate with
|vpn.modio.se||443||Remote access and debugging|
|submit.modio.se||443||Service status and internal monitoring|
All communication is encrypted with at least Modern TLS providing good security.
Other network traffic we use
- DHCP (for network assignment)
- DNS as per the DHCP server
- Possibly NTP (fine grained time sync)
- HTTP and HTTPS network probes for online checks
The device needs no routed ports or traffic redirected from the internet since there are no open ports in the firewall.
The device may listen to port 443 locally for local discover traffic (Intra-device reporting of values). The device may also listen to port 22 locally for ssh (debug).
