Thanks !

@christos

Amazing how you did this, two thumbs up

 

Where did you buy the probeholders?

@akatar

 

Thank you

 

I bought the probe Holders from PoolPlanet

 

here is the link if you are interested

these probes were supposed to be connected to the Z3 Salt chlorinator but since it was waaayyyyyyy too small i have decided to use it for my DIY project .....

 

The probe holder is quite cheap and very very beautiful ...

 

..

 

I'm Thinking of making a list of all the hardware that is needed ( i think i have already ) so if anyone wants to build one it is quite easy .... as long as there is some basic electrical skills embeded in the brain

 

The other thing i was thinking is that if anyone knows a way to build a VD in order to have better control of this, can post it here so that other members can benefit from it

With regards to the water level metering, I don't prefer to have the sensors in the water.
Someone has an idea if this sensor is compatible with Fibaro Smart Implant?

It seems the low voltage output is 0V, but they don't mention what the high voltage is.
Also, it's 4 wire connection. While smart implant expect 3 wires.

@christos Testing with a setup of PH and temperature sensor (combined in one sensor)

 

Questions: 

 

The values on the HC3 don’t seem to update. Where to look for?

 

And I have to transform the voltage of the temperature sensor to a temperature value? (Below in the picture, 4.90 is the returned voltage not the temperature)
 

What is the idea of the PH sensor housing. Should the transparant cap be taken of? 
 

On the white sensor unit there is a black switch, what does it do? (my Chinese is not that good)

heheh

 

 

I see you bought the same as mine....

 

@SmartHomeEddy ... You have to take out the transparent cap !!! just unscrew it and let the sensor read from your pond water ....that cap is for transportation or if you want to store the sensor for some time....

 

The black switch on the module is used for calibrating the sensor

 

The Ph Sensor should be calibrated every couple of months .... but for me i do it once a year at the begining of the season for my pool

 

I'll send you the calibration Procedure

 

I had to beg for the english manual

The temperature sensor is used for compensation for the Ph ....   It is ONLY used for the Module..... How do you get temperature reading in Fibaro?

 

For the Ph in RGBW sensor you just set the scale   0 volts 0Ph   and 10 Volts   14Ph

 Thanks, a lot of more info thrn the Chinese paper

I used to “T” port on the sensor unit. Don’t realy know if it’s the tempersture, but the voltage went up when I warmed it a bit up in my hand. I will look in to it.

I will have a look where on the HC3 I can configure that

 

After I have the right setup, I will have to look for some solution to hang the sensors in the pond. Some floating thing with the sensors hanging in it.

@SmartHomeEddy

 

Great

 

Tip 1

 

Make sure when you calibrate the sensor that your calibration solution is at the correct temperature  ... EG 25 degrees celcius ...

Always Use RO water to rinse the sensor BEFORE you put it in the calibration solution ...

When calibrating the sensor make sure your temperature sensor is also inside the calibration solution.

 

Tip 2

 

Your Temp Sensor should be closed by the Ph sensor in the Pond

 

The voltage went up because the Module is using tables for compensation...

 

 

I see that you have the Big Ph probe ? The black one ?

 

I also have that ...its of no use for me because it is too big to put it in my Probe holder.

 

If you want it i can send it to you so that you can have a spare one (for  free )

???
I could make a redundant solution ?

 

BTW I also have the ORP sensor, but first the PH sensor working.

Well you gonna need this too then

 

Save it !!

Looks the same from the outside

This is the “T” I get the 4.90 reading from

@SmartHomeEddy

 

Holy CRAP......... Never saw that !!!!   Jesus .... I'm so Blind .....   ok So we can grab temp also .....

 

But is that 1-10v also ??????    and if so .... what is the scale we have to set in the RGBW module ?? hmmm

 

Let me go through the manuals one more time ....

 

 

 

@SmartHomeEddy

 

There it is

 

Temperature

-20℃～+80℃

 

so for 0 volts we should put -20 and for 10 volts we should put 80

Well, I assumed, without reading the Chinese manual ?

The 4.90 is the voltage

I was so obsessed with trying to get the Ph reading that i did not see that   TTTTTTTTTTTTTTTTTTTTTTTTT      on the connector ..........   FML ?

PH Sensor and ORP sensors are calibrated on the Module from AliExpress .... they just send 1-10v into the RGBW module

 

in Fibaro configuration i have this

I think in this place, you can configure it as temperature?

 

I found it on the HC3

I am not sure about the 80 degrees Celcius

@SmartHomeEddy

 

That should be it

 

And yes .... reading from the manual you should set min V to 0 and next tab -20

max 10v and next tab 80

 

so i'm guessing it has a range of 100 degrees

 

so for every volt change you have 10 degrees change

 

the rgbw has a 0.1 volt step ( you can check in advanced settings the resolution you want it to have )  so for every 0.1 volt change you have 1 degree change....

 

try that

 

it should works

 

 

i'll do some wiring also 2morrow and see what i get

Thanks, I had the lowest value still on 0, I changed the above picture with the right values, in case someone uses the picture but with wrong values.

Check ?

@SmartHomeEddy

 

one thing you should do is do not tell fibaro to report change per step .. .. disable it .....meaning if the voltage changes by 0.1 do not let fibaro module report that ... it will crash the module ... mine crashed 3 times..

 

just set in settings of the RGBW to send report say every minute or every 5 minutes ....   that should keep the network clean ..
