I bought an RD200 last week and have been attempting to use the integration to read the sensors through ESPHome. However, I keep running into the same problems and was hoping for some advice.
After getting the ESP32 set up through ESPHome, I added the code:
esp32_ble_tracker:
radon_eye_ble:
At which point it initiates and starts searching for Bluetooth devices. However, it does not provide the expected return “Found Radon Eye RD200 device” as listed in the instructions. Rather, the device comes up as follows:
[12:54:02][D][esp32_ble_tracker:726]: Found device 24:D7:EB:5F:E6:7E RSSI=-77
[12:54:02][D][esp32_ble_tracker:747]: Address Type: PUBLIC
[12:54:02][D][esp32_ble_tracker:749]: Name: 'FR:RU22201030448'
I know this is the Radon Eye as RU22201030448 is written on the label under the device. Using the MAC address, I am able to connect to it using the yaml code:
esp32_ble_tracker:
ble_client:
- mac_address: 24:D7:EB:5F:E6:7E
id: radon_eye_ble_id
sensor:
- platform: radon_eye_rd200
ble_client_id: radon_eye_ble_id
update_interval: 5min # default
radon:
name: "Radon"
radon_long_term:
name: "Radon Long Term"
Again, the ESP32 data is uploaded and when it runs it has a hard time locating the Radon Eye but eventually does succeed. However, once it does, it reads as follows:

It’s not clear to me what I am doing wrong here. It appears to connect to the device but no data is coming across? I’m terribly new to home assistant and ESPHome so apologies if I’m missing something obvious here. Would not be surprising. I did try the same process with a different brand of ESP32 but led to the same results. I am able to access the radon levels through the app on my phone consistently. Any suggestions would be appreciated!
. I had some issues with resets/disconnects and doing to much on one esp32 writing the custom sensor as well. I always thought it is more about using wifi at the same time to BT too extensivly causing these issues. So now I am using an esp32 does only Radon. Also i found connecting and disconnecting with the BT-Device had some problems after a while as well. So custom sensor was always connected and worked in that mode over month. But it is now quite a while i was writing this code…
