Question

Hi,

It seems impossible to use third party CA for the TRB devices when trying to establish a TLS mqtt connection to a broker. Is there anyway to do this without importing the CA file each 90 days as per let's encrypt policies?

Hello,

Could you expand on “impossible to use third party CA for the TRB devices“ with exact issues/errors?

I am not particularly familiar with Let's encrypt, but there is a client for issuing Let's encrypt certificates for openWRT called acme, which you can download with the following commands (opkg upodate; opkg install acme) and configure via CLI/SSH.

Best regards,
