implementing multiple sensors
-
I combined Humidity and Lux code. Serial monitor works ok (see below) but for some reason when I try to add node to Vera I get only node, temp and lux (no humidity). I guess something is wrong in combined sketch?

One more combined sketch - UV / Light Lux. Everything seems to work ok except only 2 items show up in vera: node and lux sensor. UV sensor is missing.

There is a perfectly good explanation why UV sensor isn't showing up. MySensors does not distribute any device files for it. It might work with the rfx-plugin-device:
I remember @epierre working on the sensor, I helped him with the little sort logic on the sensor readings to determine the index... I cannot recall what device he used to present the index within Vera...
In china right now, the Great Firewall preventing a good search on the forum for that project...
perhaps @epierre can recall for you

@hek @BulldogLowell UV sensor works fine as standalone sensor / node. After trying different things I noticed that if I switch order of
these lines
gw.present(CHILD_ID_LIGHT, S_LIGHT_LEVEL); gw.present(CHILD_ID_UV, S_UV);to these below
gw.present(CHILD_ID_UV, S_UV); gw.present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);then node and UV sensor show up in vera, but lux light is missing. It seems that sensor presented 1st gets recognized but second one omitted. Could it have to do anything with both devices using analog pins?

CHILD_ID_LIGHT and CHILD_ID_UV are defined as two different nonzero numbers, right?
Sorry I cannot read your sketch here in China!!

@BulldogLowell no, they were both defined as 0. I changed them to 1 and 2 and now three devices show up. Thanks.

Good. You may be able to use zero but certainly not for both!

I think my biggest challenge is understanding when to combine the additional sensor in the main loop or when to put it in another. The whole idea of interrupts is baffling to me too.
