Possible to add existing all espresenses onto EspHome

I got many ESP32 with Espresense installed for Temp/Hum and Trackers - one device per rooms of my house. All esp32 device are hidden above ceiling with Temperature and Humidity Sensor mount at the ceiling.

thinking of adding all existing esp32 to ESPHome and can modify via Wi-Fi and able to upgrade firmware version.

How to do that - got all esp device’s MAC address and their fitted IP address - does that help, I hope ? cos I don’t want to digging floorboards up to reprogramming esp with usb. :-/

Not if you want to use espresence. It is not part of esphome.

oh right ok, is there replacement same setup what i used at moment to setup new ESPHome from scratch? Any guide to help with code for ESPHome?
need setup for Temp & Hum and Bluetooth trackers that linked to my Home Assistant vis MQTT.

i will get new esp32 and test on it to start with before i do furthers all rooms in my house. Where do i start? help would be nice… i am still learning.

ESPresense already web support and easy to amendment through there.

I used espresence for quite a while and im now using Bermuda and so far, its works just as good or possibly better and just needs BT proxy installed on esp32.

Thanks for information [Fallingaway24] - useful, will bear in my mind for that.

It possible to get code from my existing espresense and copy onto new ymal for ESPHome?

Espresense source code is here GitHub - ESPresense/ESPresense: An ESP32 based node for gathering indoor positioning and transmitting to mqtt

If you want to build some esphome custom code to emulate it, then sure, go for gold .

You are aware that this already seems to be available in espresense?

Espresence is its own firmware like esphome is its own firmware and the two dont quite get along. I would only suggest that you try both and see what you think.
