@Chris-Stratton said in Letsencrypt on Omega2:

No, you can, there or anywhere else, if you control the system that needs to do the accepting.

Yes but still I have the problem because I'm not in able to find openssl command.

@Douglas-Kryder ok so there is no solutions for the moment, right?

@Chris-Stratton Thanks for explanation!!! Just to be clear, even if I generate a certificate on Omega, I can't accept it on VPS side, right?

@Chris-Stratton See I would like to run mqtt broker for sensor in my apartment, and have a Home Assistant deployed on a VPS. Since MQTT is unencrypted protocol (also, user and password are in clear), I thing TLS is necessary. What do you suggest?

@Douglas-Kryder said in Letsencrypt on Omega2:

so, either you have no compiler or setup can not find it so that is first thing i would look into.

exactly what I thought but I don't know which package brings mipsel-openwrt-linux-musl-gcc in omega2. Searching it on google seems it comes with openwrt but there is no openwrt package for omega. Any idea?

I'm trying to setup a MQTT broker with TLS integration (Mosquitto+TLS).
After installed python-pip with:

opkg install python-pip

I'm trying to install certbot with

pip install certbot

I got an error with package cffi. The following is pip log output:

Any suggestion to fix it? Or alternative solutions to download/generate certificate for mosquitto?
