ESPhome without wifi?

I have never tried it, but what about ESP NOW?

My ESP-NOW integration library - enable direct communication between your esphome devices even without wifi router

I recently wrote a custom addon that enable esp-now integration for your esp-home devices. This add direct communication capability and you can use it along side with existing homeassistant. So in case your wifi router disconnects, or your raspberry pi stops working, your home automations will still be able to work. Check it out at https://github.com/iphong/esphome-espnow and let me know what you think. In progress homeassistant config for my actual home project Cheers!!
