Hello to everyone,
I’ve almost finished my home automation Webserver, with an ESP32 Webserver (including also AutoConnect and ElegnatOTA). Any client is able to:

• read sensors telemetries, displayed both in charts and tables;
• control actuators;
• configure the threshold values for the automatic control;
• switch on/off the actuators, bypassing the automatic control (for debugging/maintenance purposes);
• Update both the ESP32 and SPIFFS.

As soon as I have time, I will publish a tutorial on this, I think that it is customizable to different application.
I would make it to be accessible from anywhere and, searching online, the only two options seem to be:

1. Router port forwarding;
2. Use of Ngrok on other service like this.

Considering that some friends ask me to install it in their houses but without any portforwarding, I would like to find a more user-friendly solution. Furthermore, the low cost of Raspberry seems to be a good spot, if it can be easily configure by my friends. AutoConnect and ElegantOTA are two examples of User-Friendly meaning, and I want to find something like this (for the Ngrok configuration, or other solution, if any).
Now, my question:

• is there the possibility to run Ngrok on a Raspberry Pi (connected to home router), in order to make the ESP32 (connected to the same home ruoter) accessible from anywhere?
• if yes, how? Could you suggest me any tutorial (or also some different tutorials that need to be merged)?
• Is there any other way?

 
Many thanks in advance!
