This ancient imp (ca. 2013):
2322a0b236a7c9ee
went offline about 24 hours ago and has not come back. It is at a remote site so I cannot investigate in person. Elect. company and ISP both claim there are no outages of any kind at its location.
I think the remote wifi router might be failing.
The last log we have is the device failing to respond to a ping from our server early yesterday. Over the prior fortnight there are lots of wifi association retries and one 9 minute snooze due to a more prolonged outage. The RSSI looks ok and steady when it does manage to join.
Logs also indicate you are sometimes calling imp.setpowersave(true). I’m not aware of any current issue but you might try commenting that out in case the device manages to connect and fetch new squirrel.
Thanks Phil- I will check this out the next time I visit the site.
