The TRH at 250m went out last night for a bit, right as the checker script was power cycling it because the temp was high:
/var/log/isfs/dsm.log:May 1 01:34:50 250m root: temperature is -61.48 . Power cycling port 5 /var/log/isfs/dsm.log:May 1 01:34:54 250m root: temperature is 168.51 . Power cycling port 5 /var/log/isfs/dsm.log:May 1 01:39:54 250m root: temperature is 168.59 . Power cycling port 5
It came back on its own. Then this morning the Ifan value went to 0. This could have been because I was testing rserial at that time. I see some of the characters I was typing in the TRH output, such as "|fgre". So perhaps I caused this second issue. At 16:48 UTC I power cycled the TRH and Ifan came back.
