ESPHome Device Offline Problem

I have had this device working perfectly for the last 6 months or so. But this week it won’t connect to my network. I assumed the chip went bad. So I tried to connect the another of the exact same board. However when trying to get that set up it will go through installation and say it can’t connect to the next work.

I’ve tried doing the manual ip thing but that also doesn’t work.

I get the below;

ERROR Connecting to ipnumber:8266 failed: [Errno 113] No route to host

It’s an ESP-12F chip. Running ESPHome 2023.12.9 on Home Assistant Core 2024.1.6, Supervisor 2024.01.1, OS 11.5.

I’ve not made any changes that I can think of in the last few days to cause this.

Anyone else experienced this issue or able to give any advice?

Cheers folks!

Sounds like a network issue. I have had that a couple of times, and in my case it has been the Powerline link from my study to the router in the living room (that’s where the internet connection was installed).

Possibly a neighbour has upgraded their wi-fi … maybe added an extra WAP close to you and/or changed the channel they are using … which is now causing more interference than previously.

Please look in your router’s error log; and check your routers settings, particularly in case you have used Wireless MAC Filters.
