Humidity Sketch causes Vera App to crash

[Bradley A]

@hek Just a quick update. Changed the float to an int on the sensor during my lunch break. No luck. Vera still recieves it with a decimal. Confirmed with the serial console that the sensor is indeed sending it as a int now though. Perhaps the Arduino gateway is coverting it back to a float before sending it? Will do some more digging after work again

Strange. You could also try converting it to a string before sending.

[hek]

You did remove the number-of-decimal argument?

msgHum.set(humidity, 1) -> msgHum.set(humidity)

[Bradley A]

@hek Ah Hah! That did the trick. I had only changed the variable to an int but had not removed the decimal argument. Works perfectly now! Thanks @hek !!

I have the same issue. Will work on the fix when I get back.

The fix is pretty simple, as @hek said the DHT sensors arent extremely accurate anyway (DHT11 is +/- 5% accurate), just change msgHum.set(humidity,1) to msgHum.set(humidity) in the sensor sketch to drop the decimal all together. Worked perfect for me and has been running flawless since yesterday now

The fix seem pretty easy to follow. But when I exclude the "1" and recompile, I get a bunch of error messages.

Build options changed, rebuilding all

You must cast the value to int.

gw.send(msg.set((int)xx));

[jeylites]

@hek

I'm not following that part ... is it like this

gw.send(msgHum.set((int)humidity));

[hek]

The compile can't find a method matching the argument you're calling the overloaded method "set" with.

It looks at the type of the argument (float in your case).

So you can either change "humidity" to be a int when you declare it or cast it to an int.

Hello,

i see this is a old posting, but i have the same problem. But i found an error.
I use

send(summsg.set(sum));

but this work:

send(summsg.set(sum,5));
