bme680 device does not connect to wifi anymore

[r100gs]

``Hello,

I have following config, which was working fine with custom components. But now I compiled it again with homeassistant 2.11.1. It compiles fine and I can load it to my device. The problem is, that it does not connect to wifi anymore. Maybe s. b. can have a look at my bme680 config if its ok.

Hi,

Is your API encryption key a 32 bit base64 encoded string? Have you tried without the encryption?

Hello caddyblack,

thx for the suggestion. I use the key with my other devices and everything is ok. It is only the device with the bme680 which does not work ( I have only one bme680). BME280 devices works good (same key)

Best regards, Stefan

If this is still happening for you on the latest version, could you post a new issue at https://github.com/esphome/issues/issues and include the full serial logs showing the wifi connection attempts etc.
