serial number starting with RE2220

[jonathan-schmieg]

Hello jdeath!

I appreciate the work you did on integrating the RD200 with home assistant. I have a question regarding the serial number: the number printed on the device and displayed in the OLED starts with RE2220, however when I run a bluetoothctl scan I get [NEW] Device 24:4C:AB:03:20:A6 FR:RE22203281468 which shows the FR:RE part. Do you have "FR:" in your serial number as well? When I try to add your integration I get No devices found on the network Any ideas what I might be missing?

thank you for your help, Jonathan

[jdeath]

The display does not show the FR, so yours is fine.

Make sure you do not have the MAC listed in esphome BLE client section, as nothing else should be connected to it.

Turn debugging on, to get some more information:

logger:
  default: error
  logs:
    custom_components.rd200_ble: debug

[jonathan-schmieg]

I might have missed an important bit there (maybe you could add it to the readme): Do I still need the esphome client as a bluetooth proxy? I thought this integration talks directly with the RD200.

[jdeath]

You need either an ESPHome proxy or a BT adapter on home assistant box (both is fine too). Sounds like you have BT adapter on you homeassistant, which is fine. If you have an adapter, you need to see the Bluetooth integration in your homeassistant.

Many people first try the ESPHome component for the V1 (which does not work), and forget to remove the configuration in esphome.

[jonathan-schmieg]

Thank you for the quick response! I'm using a raspberry pi 4 with the home assistant image flashed on it. There's no ESP32 connected to the RD200 anymore. Where can I add the debugging stanza?

[jdeath]

Do you see the BT integration in your list? That needs to be setup.

Those lines go in your homeassistant configuration.yaml. You may already have the:

logger:
  default: error

[jonathan-schmieg]

I see an integration E4:5F:01:6B:B3:0C Bluetooth 1 device the only configuration option that I have in there is "passive scanning" which is not ticked.

I added the entire logger stanza to my configuration.yaml and restarted HA.

I don't see anything in the "UI-logs", using the file editor I only see

2023-01-06 12:53:55.324 WARNING (SyncWorker_3) [homeassistant.loader] We found a custom integration hacs which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant

trying to add the integration still results in the same error and does not add any new lines to the log

[jdeath]

Ohh, crap. Something must have gotten messed up. I just pushed another release (1.4), try that. Somehow the line looking for the spain version got changed to look for the US version. At least you'll get to the logging section now.

[jonathan-schmieg]

I updated to the new version and there's progress! I'm getting a different error message in the logs:

Going to try an esp bluetooth proxy and report back once I got the time to test it. Thank you very much for your help

[jdeath]

Also try a cold reboot of your Pi. Sometimes that can help.

[jonathan-schmieg]

Progress! After I set up an esp bluetooth proxy I was able to initialize and connect to the RD200. However it only works on the first iteration, then I have to restart home assistant and I get another reading - but also only one. Here's the logs from last night's attempt:

One thing I noticed is that on the first connection the bluetooth symbol on the RD200 disappeared after transferring the data. On the second (and all upcoming) try the the bluetooth symbol stays on but with that error.

[jdeath]

Hmm..It stays on? It is almost like it is not disconnecting. Thanks for noticing. That could be something! I'll check on mine if it happens again.

Also weird that it finds the radon data, then the next line it rediscovers the device. Not sure if that is supposed to happen. Maybe my new code I just pushed will avoid the unpack error

Confirm, it is not disconnecting. The light stays on. At now I can ask the pros on discord.

I uploaded a new parser. Please send the logs when you have your next issue with this parser. This will help me figure out why we get that unpack error, which must be leading to it not disconnecting. I also added some error checking, which hopefully will fix it.

[jonathan-schmieg]

Awesome now it seems to be working fine! I can confirm that with version 1.4 the connection was only terminated after the first try (which was successful) and later stayed open forever. Now on version 1.5 the connection gets established, data is transferred and then it's closed again. As I still have the debug log enabled I'd like to send you the output as well. There's still a KeyError: 'radon_peak' in there. It feels like something you might want to catch. The radon peak gets reported to home assistant and matches the value on the RD200 display though.

Here's two samples of the logfile - each block repeats after 5 minutes but I get the radon level in home assistant which makes me really happy! I am very grateful for your work thank you so much!

[jdeath]

Awesome! I'll look into that key error. I do not have it.

Ahh, i see the issue and why you are having a problem (and the connection issues this whole time). When asking for the peak radon, your device is not returning it. It only returns about 1/3 the data:

DEBUG (MainThread) [custom_components.rd200_ble.rd200_ble.parser] 7
2023-01-07 19:22:49.957 DEBUG (MainThread) [custom_components.rd200_ble.rd200_ble.parser] bytearray(b'@B220328RE21468\x06RD20')

Therefore, the peak key is never filled, because I now check if that is the correct 68 bytes long. I guess I could try/catch that, or fill it with None value or something. Let's see if your device ever reports it.

[jonathan-schmieg]

@jdeath the weird thing is: the peak value was reported all the time - just every 5 minutes I get this exception in the log. I modified custom_components/rd200_ble/sensor.py locally and implemented your suggestion:

    @property
    def native_value(self) -> StateType:
        """Return the value reported by the sensor."""
        try:
            return self.coordinator.data.sensors[self.entity_description.key]
        except KeyError:
            return None

Everything is still working fine but the logs are clean now. If you don't mind I would appreciate if you could add this to the code so I'm able to follow potential updates you might do. I can imagine that I'm not the only one with this issue.

Thanks again for your work!

Make sure you are not using the USB3 ports... (the blue ones), they make a ton of interferences.

@jonathan-schmieg

bef1137 Added. Will make another release in a few days

Feel free to do a PR if find anything else

[jonathan-schmieg]

@arpia49 I don't have anything plugged into the USB ports at all - but good to know thank you @jdeath will do thank you

[jonathan-schmieg]

@jdeath don't want to open a new issue just to say thanks again! I have implemented the external component like you suggested in the readme it works! thank you
