Not really sure where to start.....
I have dozens of BLE devices around my home and I've deployed BLE proxies using GL-s10's

I turn on the input_boolean switches and the logs of the ESP 32 roll by with tons of items but nothing descriptive about any of them, just a sea of payload with nothing to tell me what that device is
Example:
I tried to check the automation traces but there is nothing descriptive there, in fact it seemingly DDOS's my machine if I used queued mode :)
so I guess I am at a loss on where to start , I would love to start instrumenting some of my bluetooth devices, like my toothbrush and coffee maker but I have no clue how to tell what they are in this sea of noise. Appreciate any help you can provide
Hello, not sure what you want to achieve, but your configuration looks more or less correct and after you turn on BLE Gateway Discovery tons of items in the log it's BLE Advertisement packets which goes to Home Assistant and forwards to Passive BLE Monitor by ESPHome BLE Advertise 2 automation. As you have Passive BLE Monitor discovery enabled by default after some time you should see all discovered devices with data in Passive BLE Monitor or some messages about problems in the Home Assistant log.
If you have many devices nearby, instead enabling discovery probably will be better to add your devices MAC one by one specify (or all together without spaces) in input_text.settings_ble_gateway_add_device in this case only packets from this devices will be forwarded to Home Assistant.
You have on_ble_advertise on esp32_ble_tracker and ble_gateway sections, if you want to use MAC address filtering - remove on_ble_advertise from esp32_ble_tracker because it's forwards all BLE packets into Home Assistant. Recommended configuration example you can see here for ESPHome and here for Home Assistant.
esp32_ble_tracker:
on_ble_advertise: # <--- Forward all packets to Home Assistant, remove this
...
ble_gateway:
id: blegateway
discovery: True # <--- Forward all packets to Home Assistant, remove it and turn on when needed
on_ble_advertise:
...
Thank you very much, honestly I am not sure entirely what I want to achieve either but I am just experimenting.. I want to see what devices are near by in my home and what data they are advertising and what I can do with that data. How do I find the mac address of any given component to even filter upon it ?
I downloaded app called BT inspector for example and brought my Sonicare toothbrush near by and I got something along the lines of the following
but its not clear to me how I add this and start experimenting with it. Given the multitude of ble devices this day how does one filter through all the noise the find any particular device in general and then start exploring it to add into this tool chain ? Sorry if these are naive questions, just very new to the BLE ecosystem
Passive BLE Monitor (with BLE Gateway as remote adapter) support only BLE Advertisement and not for all BLE devices, full list of supported devices you can find here You should understand difference between BLE Advertisement and BLE/Bluetooth communication, some devices send data using BLE Advertisement broadcast packages which can be captured and parsed by Passive BLE Monitor. If device requires connection the Passive BLE Monitor can't work with such devices and you should use regular ESPHome BLE Client or Bluetooth Proxy from Home Assistant which can make connection.
To get battery % using default Bluetooth service you can use this example with BLE Client which make connection.
If your device support BLE Advertisement but not supported by Passive BLE Monitor then you can try to ask dev to add support by creating the issue here and provide all required data.
Hope this helps.
