[weewx-user] Re: SOLVED as3935 lightining module not detected by I2c on a Rpi4
Thanks Karen, Yes, it is what I understood. As I explain in my last post, I fixed the problem by extending the range to 0x03 to 0x77 by the command sudo i2cdetect -a -y 1 0x03 0x77. That works perfectly now PY Le samedi 17 février 2024 à 08:04:00 UTC+1, Karen K a écrit : > May be you want to try option -a: > > sudo i2cdetect -a -y 1 > > Adresses below 0x8 are reserved at Raspberry Pi 4.

May be you want to try option -a: sudo i2cdetect -a -y 1 Adresses below 0x8 are reserved at Raspberry Pi 4. But the lightning module can address 0x0, 0x1, 0x2, or 0x3 only. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

So... I've recently set up one of these modules from DFRobot. I started with their sample python code and morphed into something that fits in my set of libraries. In my case, I have it sending events out via mqtt. A quick look at the code doesn't give any hints to help you. >From the sample code, I set this up: #I2C address self.config['AS3935_I2C_ADDR1'] = 0x01 self.config['AS3935_I2C_ADDR2'] = 0x02 self.config['AS3935_I2C_ADDR3'] = 0x03 I think the hardware module has tiny switches to change it's address. It's dead of winter here, so no lightning to detect for a few months. I can share some of the code, but not all.

Finally, I succeeded to make the weewx running and capturing AS3935 lightning detector data For that, I had to force the detection of the i2c addresses from 0x03 to 0x77 instead of 0x08 to 0x77 with the command: sudo i2cdetect -a -y 1 0x03 0x77 I had also to add gpio to weewx group: sudo usermod -a -G gpio weewx PYB Le vendredi 16 février 2024 à 21:30:08 UTC+1, Pierre-Yves a écrit : > Hello All, > > Maybe a bit off-topic.
