Can I plot a temperature that I scrape (time control set to 5 minutes) off a weather service?
I am copying the example on thingspeak read and write, where I scrape the temperature of my town from a weather service. I set time control to do this every 5 minutes and then send it to my field 6 in my channel. In the example given in thingspeak, Natick MA is used, and I changed that location to my town. Everything works well and I am able to display my local temperature as a widget on my channel, (chart or gage or numeric.) But when I try to plot the temperature, the plot is blank. My data microprocessor for my lab is sending data every 25 seconds or so on 7 fields. (1,2,3,4,5,7,8) The 6th field is the scraped temperature. I can plot any of the other fields. When I do a csv data dump, the data looks like this:
FIELDS— 1 2 3 4 5 6 7 8
2023-12-06T22:12:06-05:00 600020 36
2023-12-06T22:12:29-05:00 600021 59 55 55 0 0 -0.61 0
2023-12-06T22:13:08-05:00 600022 59 55 56 0 0 -0.60 0 etc, etc…
So, every 5 minutes, field 6 gets a value. The other fields get a value twice a minute or so.

Note: We have not started the boiler yet this season because we have a lot of fire wood we are burning in the fireplace heater.
