garage sensor box, notes before I forget

Box is a Pi Zero in a plastic junction box, on the shelf above the door. - BME280 on i2c, address 0x76, cable is 30cm which is about the limit before it gets flaky - writes to local sqlite, porch box pulls over ssh every hour - condensation got inside once, drilled two small holes in the bottom, no problem since - SD card is on its second year. Should probably replace before it fails and not after - read-only root would be nice, haven't done it

30cm is fine at 100kHz. If it gets flaky drop the pull-ups to 2k2 before you change the cable.
