127: IOT — Things That Fail

Where shall I start? Most common or most irritating?

1. Irritating: I’ve had 2 Rpi micro SD cards fail. All the way, can’t retrieve data, can’t even be reformatted. Been running continuously for several years. Mostly but not totally backed up. Drat!

2. Common 1: Cheap (and not so cheap) relay boards. They just don’t make it in my farm-hoophouse world of wide temperature/humidity swings.

3. Common 2: Temperature/humidity sensors — same problem. I'm on my 5th type. Maybe ok.

4. USB power plugs: surprising — or not, because they are cheap.

5. Soil moisture sensors: unless you just replace them regularly.

6. Raspberry Pi wifi — 2 failed. Also one Pi itself.
