How can I use with Passive BLE Monitor integration when using esphome only (not the rpi 5 bt )??

@alon24 The example from ESPHome which uses ble_client not really helpful here because Passive BLE Monitor can't connect to device like ble_client and can only receive and parse BLE advertisements.
What will be helpful for @Ernst79 it's a whole packed data from BBQ Probe which you can get from your ESPHome log, look for messages like below, just be sure that you grab messages from BBQ Probe in your case as I see from log it's 2A:03:4E:CF:0F:38
Also write temperature which you seen at the probe, this will helps to understand where it's located in advertisement message.

Also logging multiple log lines helps figuring out where we can find the actual temperature data, as I can than see what changes and what not

Seems to be the same BBQ probe I reverse engineered almost two years ago ;)

theengs/decoder#149 (reply in thread)

Due to the connection NOTIFY requirement this is not possible with ble-monitor, Theengs Decoder and the Theengs App, which all solely handle BLE advertising data decoding.
