Remote access HASSIO + NGROK help

Hello everyone,

i have just tried to reach my hassio (on my raspberry pi) behind a 4g router in CGAT…the only “free” way it worked it was going in the shell and:

cd /tmp
./ngrok authtoken <MY_AUTH_TOKEN>
./ngrok http XXX.XXX.XXX.XXX:8123

And it work!

So how can i set this in hassio?beacuse each reboot the TMP is deleted.

Thanks to all
