I had this working but recent weather events weren't popping up as alerts on my dash. When I went to investigate, I am sure I broke something, then fixed it, and broke it again. I could use a sanity check. The flow is very simple: Go to NWS alerts.weather.gov page for a county, check to see if the…

Thank you. I went to that link and followed the info. Instructions don't work for chromebook for some reason, so I did it manually. Great start. The HTML node outputs the right alert when it is available, but I can't get it to pass anything other than FLASE to the alert, when it used to pass the …

What type is the string node? node-red-contrib-something probably. I notice that the information you are want is in msg.payload[1], have you allowed for that in the string node, also the Switch node after the string node is testing msg.payload[1], is that correct? [image] bodylinksystems: I w…

[image] Colin: I notice that the information you are want is in msg.payload[1], have you allowed for that in the string node, also the Switch node after the string node is testing msg.payload[1], is that correct? Thanks for the reply. So I found that if I checked the entire msg.payload up fro…

When debugging the first thing to do is to find out which node is not doing what you expect, so add a debug node showing what is coming out of the string node. You can test it without waiting for an alert by using an Inject and a Change node to build a test message to pass in to the html node (or t…

In fact, having installed node-red-contrib-string I can see that you are testing msg.payload, but in fact the string you want to test is in msg.payload[1]. So that is not going to work. Also note that you can use the builtin Switch node to do the test, you don't need to use a contrib node.

[image] bodylinksystems: As it is now, I get an udefined return from the text node That is because it is expecting msg.payload to be a string, but it is an array. The easiest fix is probably to put a change node before the string node, to move msg.payload[1] into msg.payload.

[image] bodylinksystems: Are you saying I can remove the text node and just use the switch mode? I think the main confusion is that there isn't even a payload[1] unless there is an alert. Yes, The switch node can look for a string in msg.payload[1]. Also, when I run your flow I see, in msg.p…
