I noticed only after a few weeks that my uradmonitor was no longer able to send data, due to a problem with its network connection. I’ve looked for a solution to alert me when uradmonitor.com has not received data from my unit for a while, and came across uptimerobot.com: If you make a free account at uptimerobot.com, it allows you to monitor up to 50 user-defined services periodically and alerts you by e-mail when they are down.
I found out through a bit of experimentation, that the URL http://data.uradmonitor.com/api/v1/devices/11000001/cpm is used to grab the data for the CPM graph, and normally responds with JSON data in the form
[{"time":"1451319871","cpm":"17"},{"time":"1451320470","cpm":"14"},{"time":"1451321070","cpm":"17"}]If the unit is down and no data has been received for a while, it seems the JSON response instead is
{"success":"[]"}Of course, replace the 11000001 in the URL with your device id!
So you can set up an UptimeRobot as such:
Monitor Type: Keyword
Friendly Name: my uradmonitor data feed
URL: http://data.uradmonitor.com/api/v1/devices/11000001/cpm (use your device id instead of 11000001!)
Keyword: success
Alert When: Keyword Exists
Monitoring Interval: Maximum (120 Minutes)Attachments:

That’s a good approach, however I’m not sure on how often the monitoring site calls the API.
If too often, it might trigger the DoS protection and get ignored (interpreted as a sigh of deliberate server resources consumption).EDIT: Indeed if there is no recent data, the JSOn answer will show an empty array (no matches).
Hello Ken,
The model A has a watchdog mechanism: if the network connection drops, it will reboot automatically after 10 minutes. This was added in the newer firmware versions, and your unit has it.
I’d need more details to know what goes wrong with your setup, and a first thing you could test is connecting the unit to a different internet router. Then is changing the power adapter with another one. We’d need this two ruled out before anything else.
L.EDIT: I see it up and running: https://www.uradmonitor.com/?open=110000E7
I am not thinking the watchdog is working. It has dropped out several times over the past few weeks and I have to hard boot it to get it to come back. Currently offline again.
Is there a way to update the frmware? I know you said mine already has it, however it does not appear to be functioning as you described.
