I should add a status metric to know what the actual error code was (e.g. failed I²C acks vs. error status vs. timeout).
It's raining again and yeah, looks like the BME280 is not acking I²C transactions. Probably water ingress. I'll print a shield for it tonight.pic.twitter.com/npmp5DF7Ka
Hotglue it to a glassjar bottom and let it be upside-down?
Self programmed or using some kind of ready project? I searched a little bit but gave up and ended programming something simple with arduino for the esp32 to read 3 sensors and send it to Influx.
Self programmed. ESP8266 + BME280. I tried using the Arduino environment but it is fundamentally broken for this kind of application (no power management or event-driven server support) so I switched to the raw ESP8266 SDK.
stop hogging all the rain!
scrub question: any particular resources you'd recommend to someone who is just getting into I²C, SPI, GPIO, and similar? I have hooked up various things to raspberry pis following instructions, but I'd love a deeper understanding of all this.
Read actual part datasheets and protocol spec documents. They tell the real story :-)
Could it be humidity ingress too? When it stopped was at 90%
The sensor is specced up to 100%, but I don't think it likes actual liquid water. It seems to work again once it dries out though.
