Wireguard VPN Client for remote Zigbee device reporting

[Fayrewood]

Hi,
I would like to install my Tasmotized Sonoff ZBbridge at our local marina and monitor various Zigbee sensors via MQTT.

The Sonoff would be simply a guest device on the marina's wifi and there is no chance that they would allow me to set up a site to site VPN on their equipment. I have Wireguard installed on a server at home and would like the remote devices to report back to my MQTT broker securely using the VPN key exchange.

Is it possible to configure Tasmota to establish a wireguard VPN once it has connected to the public marina wifi?

Many thanks,
Pete

What Tasmota supports instead is TLS Secured MQTT.

Wireguard is now available: #23347 and https://tasmota.github.io/docs/Wireguard/

Hi everyone,
I compiled a version of Tasmota for the ESP32C3 with Wireguard enabled, but as soon as I run the WGConnect command, the ESP resets.
The wireguard.conf configuration is correct, as it works when imported into a Windows client.
Any suggestions?
Thanks.

It's just this line:

It looks to me like the problem is specific to the C3. The WG connection works with a D1mini, but on the ESP32-C3, it reboots when calling WgConnect in the console.

But even on S3, it's not stable and causes resets. I'll send the requested files this afternoon to try to solve or identify the problem.

@s-hadinger Here is the link to .map:

at this time, even though I have done some reboots (unplugging the power) it seems that the problem is not present

Update: Without changing anything, the device has been working normally for 1 full day
