Hi,

I am a total novice with JS, but have re-arranged the weather module to display my home weather station data instead of OpenWeathers data. The module works, but I’m having issues with it intermittently updating the data. In other words, the module will work and update fine for several days (or hours) and then will stop updating, and will show the same data until I restart MM or the pi. The other modules work fine on the MM, and per the weather station API page, I’m not exceeding the call limits. Only error I’m seeing on my Chrome console is:

“Uncaught SyntaxError: Unexpected end of JSON input
at JSON.parse ()
at weatherRequest1.onreadystatechange (MMM-AW.js:187:30)”,

which to be honest I’m not sure what it means…

Appreciate any help! My config is attached. ```

@mumblebaj

The data I get back is just numerals, with the exception of wind direction, which I convert to cardinal values :

(temp) 48.6
(wind speed) 2.2
(wind direction) NNE
(feels like) 48.6
(daily rain) 0

Although with @sdetweil help, and using conditionals, I’m able to see my data on the MM now!

@sdetweil

Thanks! I’ll give that a try!

Hi - trying my own spinoff of the weather modules to pull in my home weather station information. I’m still learning JS, but have been getting the hang of it…

I’m able to parse my preliminary values (as I’ve been able to show by logging it) and have been able to send them to my updateDom section (again by logging), but I haven’t been able to get my “feelsLike” and “dailyRainIn” to update at all. No matter where I try putting it in the appendChild code for these values, it won’t update to the MM. My temperature, wind speed and wind direction do properly log.

I’ve racked my brain trying to figure this out and changing the combinations, but can’t solve it. Any help would be greatly appreciated! Thanks!
