emonpi

Network devices such as an emonPi connected to a local network are secured behind a firewall, often integrated into a router.

The conventional way for obtaining access remotely is to open a port in the firewall and 'port-forward' requests to this port to the local emonPi. This method works but is cumbersome and insecure. It's cumbersome because most users connect to the internet via their ISP using a non-static IP. Therefore the WAN IP address often changes, a dynamic DNS service such as Duck DNS, or noIP can be used to link a dynamic IP to a static domain name, however this is cumbersome to set up and often requires purchasing a domain name, dynamic DNS Subscription and handling the dynamic DNS IP address updates.

The port forwarding method of remote access is also insecure since by default the emonPi uses an insecure http connections, this is not a problem on a secure local network but not recommend for use over the internet.

Dataplicity
