ESPhome without wifi?

[janbenes]

Hello. I would like to use esphome sensor in environment where is no wifi. It communicates only over SMS. How do I configure wifi component? I know it is mandatory, but when I enter invalid SSID or password, sensor does not proceed to GSM initialization and only restarts wifi in a loop.

The only way you can use ESPHome without wifi is by using one of the supported Ethernet boards. Not sure what happened if they don’t get a connection via that method though.

How do I configure wifi component?

Maybe just by using the ap mode?

WiFi Component

other option is to use this pr (merged in esphome dev) which allows to enable/disable 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!!

and only restarts wifi in a loop

Disable the reboot_timeout

I always forget about that option.

Why not use an Arduino board then? Or is there a specific reason to use ESP board?

[orange-assistant (the real one)]

The biggest problem with the arduino boards is they don’t run ESPHome

[janbenes]

I solved it. Thought the wifi component is mandatory, but it is not. So I have removed it from yaml.

Hi.
I’m thinking of running without wifi and connecting via ISB only. Any idea how to do it?
