About DS18B20 onewire.

@flopp
Hi
Tell me... is any chance to add in sketch position to write description for sensor and to send this description to Home Assistant....? It is ok write in other sketch for relay and it works perfect:
https://github.com/lkankowski/arduino-multi-relay/blob/master/arduino-multi-relay.ino

It show in Home Assisnatn this information in description example: Ł2 - kinkiet [C10]

mfalkvidd

@pepson yes. Just change the present call, just like in your sketch.

Example: change

present(i, S_HEATER);

to

present(i, S_HEATER, "Description goes here");

pepson

@mfalkvidd
OK but also must add defined description to all address. But how add also description?

Don't know, if that really works, because I never tested it since my controller sw supports comments: https://github.com/rejoe2/MySensors-Dallas-Address-ChildID-Consistency/blob/master/DallasTemperatureSimple/DallasTemperatureSimple.ino

pepson

@rejoe2
But where in sketch you define address and description ?

rejoe2

@pepson That's not necessary: The sketch reads the bus to get all the necessary info and will just send whatever is found.

If you want a "hardcoded version", you'd have to addopt the sketch for something in between these variants: if you use an array for the 1-wire addresses like https://github.com/rejoe2/MySensors-Dallas-Address-ChildID-Consistency/blob/master/Dallas_Addresses_Array_Solution/Dallas_Addresses_Array_Solution.ino does, just built the comment char-array based on that info.

Ok i know how add to present description , but still dont know how add description to each sensors.... as in sketch for relay as i show as example.

rejoe2

@pepson I'd suggest you make a test with the "simple" variant of the sketches. Then we could lateron discuss how to deal with an array containing the hardcoded addresses.
Pls. make also a test with the hardcoded version. Afai remember, it will print the needed array to serial, as long as #define PRINT_ARRAY isn't commented.

pepson

@mfalkvidd Can you help me... or change it ?

@pepson you have a stray } after setWaitForConversion

Tip: use ctrl+t in the editor to easier see this type of mistake

pepson

@mfalkvidd
Still is problem after use CTRL+T

@pepson you’re missing a } before start of loop.

pepson

@mfalkvidd
Where ? please show me more.... :( i am beginner

pepson

@pepson ok fixed it :)

pepson

But.... Can you also help me to add to this sketch option to send to example to Home Assistant also DESCRIPTION to each sensors ? And description will be get from sketch from name about address sensor ?

As in this sketch which i have for relay:

And in Home assistant show example decription: Ł2 - kinkiet [C10] or for second Salon 2 [A9] etc.
Please help me... because it will be good to identify sensors when add to Controller.
