[kidltt]

Hi, sorry for my poor English.
I have create a home iot device to control the light and fan, but Wifi in my apartment sometime not stable. I want to connect my RainMaker device using Lan cable but unssucessfull. Have anyone done before?, please give me some hint, thank you.
What I have done:
- I useed Wifi provision to accociate with RainMaker app and worked perfectly
- After that I change Wifi to ETH in setup function. I used to do it before and have no problem with Telegram bot example, google Firebase example, but not work with RainMaker
- I am using Arduino Framework, I also tried with ESP-IDF but same result
