Typically, I have to cut power and wait to get the sensors working again. Sometimes even that seems not to work.
Here's the i2cdetect: it looked the same a few days ago when I was setting it up.
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: 40 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- 63 -- -- -- -- -- -- -- -- -- -- -- --
70: 70 -- -- -- -- -- -- --
And, right now, I have only the 'bare' DS18B20 connected, and I see a bunch of these messages in the log:
6/19/2021, 7:16:58 PM UI ERROR {"error":"open /sys/bus/w1/devices/28-3c01d075740d/w1_slave: no such file or directory"} | HTTP 404
For some additional diagnostics, as you suggested I removed all external cabling, plugged in a second 'bare' 1820, rebooted and got NO temp readings. So, I removed both temp sensors from the configuration and re-added them, and they started fine and have been reporting and graphing for 15 mins, or so. I need to hook the lights and pumps back up--we'll see what happens w/those connected. Clearly there is an issue where the pi somehow decides to de-register the driver after some kind of a failure.
I'll report back when I've got some new data.
