linksys-e8450-openwrt-installer VS openwrt-configuration-ansible

My Belking rt3200 was working perfectly for months. After following DangoWRT's install process, I was able to use the provided AUC script to update twice (Performed via webUI). However, I let the device run continuously for several months without a reboot. My wife left for a day (about 10 days ago), so I thought I'd take the opportunity to let the router update itself again. However, running the internal "attended update" in Luci failed for some reason, I can't remember exactly. I might have notes saved somewhere if it's important. Anyway, I returned to u/DangoWRT's GitHub page and noticed an area that said "If you are not interested in building yourself, the pre-built files are available here." So I followed that link and downloaded the latest v0.6.5 update, and flashed it to the router.

I have something similar: https://github.com/danielvijge/openwrt-configuration-ansible Using an ansible playbook this can configure multiple devices in the same network. But this uses the default configuration files, sometimes with JINJA2 templating when required. For me using the same config format as on a device is convenient, because it allows to first configure using (l)uci, diff the config, then store it.

I use this setup with one router and (currently one) access point. The GitHub description lists the exact configuration. The ansible script is there to push the same configuration from a central lcomputer to both the router and multiple access points, but is totally optional.

https://github.com/danielvijge/openwrt-configuration-ansible might help. I did it with routers as AP, but can work with RPi's too I think.
