Please share example .ino with multiple DS18B20?

[michap]

In 2.07 will be a 1Wire scanner (will scan for 18B20 addresses) and the array issue is fixed.
So you can replace soon the sketch with the new sample code

Hi,

Thank you! The sketch you uploaded seems to work! I'm really thankful for your help. Maybe your sketch could be featured in the https://z-uno.z-wave.me/examples/ to help other users? I assume there must be several other users who want to use the Z-Uno with multiple temperature sensors?

no problem. The funny thing is that yesterday evening the beta 2.07 was released and from the description it will work with multi-dimensional arrays, so I expect that your code will compile and run under 2.07 as well ,-)

So you might want to give it try...

If the new compiler supports the arrays, "your" code style will be much better as an example.

For the Vera stuff I can answer, I don't have one and I don't know how it organizes the devices. I can only say that from my system (fhem) I get a "root"-device e.g. 52 and then "children" 52.01, 52.02, ... where the functions of the first child 52.01 are also mirrored into the root device.

Regards,
Andreas.

Does this new FW means that you won't have to specify the DSB1820 ID:s? HOw do I update the Z-Uno to 2.07? Is that the same as "Burn Bootloader"?

HOw do I update the Z-Uno to 2.07?

See the topic from PoltoS https://forum.z-wave.me/viewtopic.php?f=3427&t=24150
After updating software you must burn a new bootloader.

Yes, ID's will be detected then.
I would wait a little bit - if you want to be sure - it is a release candidate only - and the samples are not online just now.

Hi,

yes, waiting a litte seems to be a good idea as it seems that there are some issues with 2.07 that are not fully explained...
I have a 2.07 now on my normal machine but can go back to 2.06 on a linux server or on my laptop...

Regards,
Andreas.

Not having to manually define the sensor ID would be very helpful. The DS18B20 probes I want to read is connected to warm water tanks, and I can't reach them easily. I will wait until stable FW 2.07 and try again. Maybe there will then also be some better example sketches from Z-Uno manufacturer.

With 2.07 the provided sample code (in IDE) is working fine
No more needs to define the addresses before - will be scanned.

For debugging via USB edit the line

Code: Select all

#define MY_SERIAL Serial

Great!

I managed to update to 2.07.

What sketch should I upload to the Z-Uno to automatically scan and send temperatures from multiple DS18B20? I have these examples in IDE:

"DS18B20Scanner" of course

Weird. I have uploaded this example to the Z-Uno but I don't get anything in the serial monitor? I have pressed the reset button after uploading and tried to disconnect the Z-Uno from the computer.

However, am I wrong to assume that that sketch seems to scan for DS18B20 ID:s? I have already found out ID using other sketches. I thought 2.07 would be able to find 1-wire sensors automatically in sketches?

I would like a sketch that automatically find multiple connected DS18B20 and send the values to my controller.
