Question on noise level about lightning-detector-mqtt2ha-daemon

[ironsheep]

Julian,

Please refer to the manufacturer datasheet for the detector chip. They have the most accurate explanation of the disturber settings. Generally, I don't worry that the script is adjusting that value.

Regarding the calibration values grab a copy and paste them here. I'll take a look. It's been a while so I'll have to look things up after you provide what you are seeing.

These are the values I'm getting:

In Home Assistant the MQTT sensors all show as Unknown. Is this normal?

It looks like your values are just fine. The detector board, how your hardware is organized, and your electrical environment all play a part in altering the values determined by this script. As long as the script finds a solution you should be good to go!

Thanks for the response. Did you see my question about the MQTT sensors? They all show as Unknown. Is that normal? We had a thunderstorm yesterday and my Blitzortung integration showed lightning strikes close by, but the values on all of the sensors from this integration never changed. And I'm not actually sure which sensor to use with your lightning detector card. I'm assuming it's the sensor.lightningdetector_count and sensor.lightningdetector_last, but your directions for the card don't actually say which sensors to use.

I have your RPi reporter software and monitor card installed on about 20 raspberry pis around my home, so I just sent you a tip. I really appreciate your help with this.

HI ok, if you are getting unknown the no data is being reported from your detector.

The python detector sense and report via MQTT script has a debug command parameter which you can enable to see whati's happening ... look for any problems when the script interacts with the detector.

Regarding which sensor to use I've added an example configuration that I use to the top-level README so you can see what I have that works. See: https://github.com/ironsheep/lovelace-lightning-detector-card#card-configuration
