      Hmm, the sensor failed during the rain earlier (but now it's back). Water ingress? The host was up, but no temperature readings, which means the BME280 was failing to acquire measurements but was otherwise up.pic.twitter.com/w276AnJddA

      I'm guessing water entered the sensor opening. I need a radiation/weather shield anyway, so that should take care of both the sun and rain problems.

      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

      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.

          Yep I know, I did a crappy and fast program using the arduino classic loop and a sleep and I have some issues with Wi-Fi. Eventually (having a look to my eventually backlog this could be never) I would want to use the raw SDK.
