Feature: proxy ble bthome packages to Home Assistant blemonitor integration

[afarago]

As in the past few months I understood the HCI capture format there is are no more obstacles to receive a bthome package and on the receiver node (ble or more likely beethowen/esp-now) create a BLE HCI package and proxy it directly to the blemonitor integration.
As it requires no additional component, just a service call the receiving node can be an ESP8266 as well.

Next step would be proxy it directly to the BLE stack of HA - yet I lack this knowledge yet and were not able to get info from the forums yet.

I'm keen to see this happen at some point, and when I get some time to dedicate to this part of a project I have on the back burner, I hope I might be able to chip in a little.

I really like the approach you've taken, and I feel it's the "right" way to bring ESPNow to esphome/ha. Integrating the BTHome protocol is a perfect fit, imo - and being able to then inject the received BTHome packets as if they were BLE adverts is chef's kiss 👨🏼‍🍳 💋

I've got a number of Lenovo battery-powered PIR sensors that I want to reflash to make them a better product. They use the TuyaMCU (low-power variant) and an esp8266 to send motion events via wifi, via the cloud. It's no wonder they ran a fire sale on the things, between wifi and cloud they would provide a terrible user experience :-)

My plan is to:

• Put esphome on the devices
  • have it talk TuyaMCU low-power mode to the mcu
  • send motion and battery events/data with BTHome over espnow using your beethowen-transmitter component
• Deploy several esp8266 or esp32 espnow-proxy's running esphome
  • receive BTHome over espnow using your beethowen-receiver component
  • forward those BTHome packets as pseudo-ble adverts to HA using the bluetooth_proxy api.

I have esphome running on the device, but the tuya mcu component doesn't talk the low-power variant of the protocol (yet), so that's where my available time will go for now - although I've other projects that are getting priority currently.

Anyway, I know all this is rather off-topic for this feature request, but I wanted to ping you and let you know about at least one potential use-case, and some moral support :-) Hopefully it will inspire some more collaborators to jump in, if nothing else :-) If I get further along with the other parts of the project I'll see if I can help out with this part of things, too.
