I managed to get the ESP8266 firmware up to a reasonably usable state this week. You can find them on my github here.

The ESP8266 is set up to communicate over MQTT (shoutout to Elliot for his wonderful mini-series on MQTT). Button and relay operation is prioritized higher than any networking features since these are the primary functions of the device. The repo is likely to be updated quite frequently as I prepare for installations in September.

Right now I'm playing around with my broker/hub configuration. The hub project page will be seeing more updates when I find a configuration that I like.

That's it for now. As always, chat with me if you got any ideas!
