see solution above. Delete your dallas library and replace with the one above in the master zip file. That was the solution for me.

Now testing for few day's and i see that one of my sensors stops working after few minutes.. the one that is most close to the gateway... after resetting it sends af few minutes and then stops working again...

no need to change anything on your original sensors and and yes it will relay signals from multiple sensors to your gateway/controller. Just our of curiosity, what controller are you using???

Just build the repeater today..how can i see check if it is working properly??

Nevermind its working :):) just received the information on the repeater... great support thanks

Using pimatic v9. on a raspberry pi 3. I already build a mysensors combined temp/ph sensor. But had to change the code in mysensors v2.0. I'm using lot of 433mhz over more then 25 devices.. but im now changing also towards mysensors :). so the mysensors is a little bit new to me.

stingone

@ramoncarranza

Ok so no need to change any code in my original sensor? and will it send multiple values from more sensors if picked-up?

stingone

@ramoncarranza

So just using that example code is enough?

@scalz said:

Hello,

Here it is https://www.mysensors.org/download/sensor_api_20#create-repeating-nodes
lot of great docs on main site though

so do i need to use for each sensor a repeater? copy the sensor code and add the #define MY_REPEATER_FEATURE in the top of the code?

stingone

@Boots33 said:

@stingone That is a known issue with the latest dallas library. See this post for the fix

Many thanks.. works all fine now had indeed the wrong datasheet...

stingone

Hello everyone.

I cant find a clear solution how to build a repeater. i have a tempsensor on 40m distance from my gateway and want to build a repeater in between.

Can anyone tell me what to do achieving this e.g. sample code etc..

Thanks..

stingone

@Boots33
Will check the wires again...
what about the compile error?

int16_t DallasTemperature::millisToWaitForConversion(uint8_t)' is private

I did a fresh install with latest libraries.. but still getting this error everytime while compilling.

stingone

Hello everyone.

Today i tried to create temp sensor... i did it before for my fishtank all worked fine.

Today i used a DS18D20 incl 4k7 resistor. After hooking-up the sensor burned down right away... hooked-up to the 5v. Also getting no information from the serial monitor....

I already flashed it to a gateway to see if my arduino and NRF24 still was working and it did. so i have no clue what goes wrong here...

Any suggestions before burning more sensors...

stingone

No compile error but i cant see anything on the serial monitor. also the temp sensor burend out with a 4k7 resistor :S

@mfalkvidd said:

It depends on how much work you are prepared to do and how much flexibility you want in the code.

If you only use one temperature sensor and don't have any plans to add more, change
gw.send(msg.setSensor(i).set(temperature,1));
gw.send(msg.set(temperature,1));

Only using the ph sensor and 1 temperatuur sensor no need for more temp sensors.

stingone

@mfalkvidd said:

@stingone this line
 gw.send(msg.setSensor(i).set(temperature,1));
will set the child id to 0 for the first temp sensor, to 1 for the second and so on. That's why you get temperature data on id 0, which is also used by the ph sensor.

What would be best to do?

stingone

Got it working with another laptop..wil recompile to 2.0 in the weekend.

Just a quick question. I have 2 sensors on 1 arduino. Works fine however sometimes it shows the value of the temp sensor on the value of the ph sensor.

If you look at the output in pimatic you can see that the mysensorsPH and mysensorsDST have the temp value. This happens 50% of the time.

Hello.

It seems that you have not converted your old sketch to 2.0 In the new release there is no need of declaring a Mysensor instance like before "Mysensor gw" and some other stuff ..

So, what you can do:

convert your sketch to 2.0. For details see here : https://forum.mysensors.org/topic/4276/converting-a-sketch-from-1-5-x-to-2-0-x

or look at the 2.0 examples sketch to see how it looks now. and don't worry if there is not so much code in new sketch compared to before, the stuff is hidden that's all

If still issues, please post logs so we can help you. without not easy..

I will try to change the code. for now i installed the 1.5 again however compiling is fine but it says at the end error uploading sketch thats all no other messages.. i already tried 3 board other usb cable. com ports settings are fine and i can use the serial monitor with the existing code but somehow it wont upload the new.

Hi everone.

Couple of months i created a code for my dallas an ph sensor. however i reinstalled my pc and installed the mysensors 2.0 resulting in a error with No forward link or gateway feature activated.

Re: PH and Temp controller with arduino

Hi everyone... couple of months ago i started working on a PH controller and temp controller. I finally got it working including in Pimatic.

You can find the whole how-to, part-list and combined sketch in here.

PH and Temp controller for Pimatic with mysensors (how-to)

@TheoL said:

@stingone I think it could be achieved by a relay. I know from the guy from hackaweek at youTube, that there can be peaks of up to 50V on a telephone line. I don't know the amperage, but you can measure that.

Normaly its arround 40V DC between A and B
When being called 40V DC + 20 AC 25Hz.
When the line is open it drops to 10V DC

Amps is arround 30mA

Dont know what kind of relay to use to achieving this.

Hi everyone.

I'm looking for a way to switch on/off my telephone line. As we have a litte baby we dont like to be desturbed after 8 PM. i thought about a swith in the telephone line. any ideas?

These are the reading i got.

send: 2-2-0-0 s=255,c=3,t=15,pt=2,l=2,sg=0,st=ok:0

The 14.79 is from the PH the rest the temp sensor.

as you can see both values are on parent 0. is it possible to get the ph on parent 0 and the temp on 1?

Hi everyone,

I just got a compiled sketch with a ph sensor and temp sensor however i push the values to pimatic. however i have the ph meter as child id 0, and the temp as child id 1. however it seems that both values are on child 1.

Can anyone have a look at my sketch to see where the error is?
0_1460752368057_PH_Probe_v1.1.ino.ino

Just found is however this one is based upon 3.3v im using 5v.

Re: Mysensors P.H et E.C prob

Hi everyone. I try to read my ph probe values from my arduino. However the files above are not working. I also used the test code however this is not incorporated in the mysensor files. can anyone supply the correct ino file?

stingone

Thanks still need to find out where to start and if i need a uno or nano. i also want to make it wireless. and indeed i want to submerse it permanent. i will buy a better one

Hi everyone.

I want to start a project with regards to ph and temp controller for my aquarium.

I found the following hardware on aliexpress http://www.aliexpress.com/item/1pcs-lot-Solution-PH-valuo-Temperature-detector-sensor-module-for-arduino-free-shipping-Free-shipping/2035918221.html?spm=2114.031010208.3.54.MxpRSV&ws_ab_test=searchweb201556_3,searchweb201644_5_10001_10002_10005_10006_10003_10004_62,searchweb201560_6,searchweb1451318400_6150

I want to connect this to a arduino and send the data wireless to my raspberry pi and capture the data in pimatic.
