MMM-BM-OW when 'no rain' for forecast undefined message received.
-
Hi,
I added + forecast.daily[0].rain + “/mm Rain” to the MMM-BM-OW module and if there is rain the amount is returned. If there is no rain I receive “undefined”. I would like to show " 0 " (zero) or at least something, but I haven’t been able to as yet figure out how to do it. Anyone have some pointers?Cheers.

MMM-BM-OW
I can take a look at it if you’d like.
-
Sure, thanks.
I tried a bunch of things and was just thinking about “null” being returned and how to handle it. If rain worked completely then I could try snow and that would cover everything ( I think) I’d want the module to do.

Just to be clear, the module works but not after you modified it?

Hi,
The module works just fine. It’s only when you do not receive a forecasted rain amount . So if Tuesday has 2 returned ( for mm of rain) and Wednesday has no rain then Wednesday displays undefined as a value.
The code is …
moment.unix(forecast.daily[X].sunrise).local().format(‘ddd’) + "  " + “<img class = image src=./modules/MMM-BMW-OW/icons/” + forecast.daily[X].weather[0].main + “.png>” + "  " + Math.round(forecast.daily[X].temp.max) + “/” + Math.round(forecast.daily[X].temp.min) + "          " + forecast.daily[X].rain + “/mm Rain” + “         ”+ until 6 terminates with no + but with ;
Hope that helps.
is 0 to 6. -
That check mark is supposed to be X for 0 to 6.

Hi,
I changed the string a bit. I added Math.round to forecast.daily[X].rain + “/mm Rain”
Math.round (forecast.daily[X].rain) + “/mm Rain”
and instead of undefind/mm Rain I now receive NaN/mm Rain.
Cool.

@scumbelly this needs some css help but… is this what you’re after?
-
Exceptional. That’s it! What’s the solution? I started to go down an isNAN() rabbit hole but as yet haven’t been successful.
Great job.

@scumbelly It takes rewriting parts of the entire module to make it work…
