You can use any name service provider which has an API to automatically add the txt record for certificate renewal. See the wiki page on [DNS API Mode](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert#5-dns-api-mode).
Since the Router shell is very limited, there are several constraints. the most important of all, there is no crontab. Since the Router shell is very limited, there are several constraints. the most important of all, there is no crontab.

since there is no crontab, we need to manually add it to cron. since there is no crontab, we need to manually add it to cron. The Let's Encrypt cert expires in 90 days, so the recommended renewal date 1 month before expiration, i.e. every 2 months. Use a [crontab tester](https://crontab.guru/#3_2_1_1,3,5,7,9,11_*) if you need help with this part. The following updates the certificates at 02:03 on the 1st day in January, March, May, July, September, and November.
``` ```
$ vi /etc/crontab $ vi /etc/crontab
and add something like 3 2 1 1,3,5,7,9,11 * root /volume1/@appstore/acme.sh/acme.sh --cron --home /volume1/@appstore/acme.sh
3 2 * * 2 root /volume1/@appstore/acme.sh/acme.sh --cron --home /volume1/@appstore/acme.sh
:wq :wq
