Hi all! at the end, the sensor board seemed to be broken, so I ordered a new one, which is working in esphome with readable ph outputs. How can I convert this to es-easy? I tried it with the ads plugin, set to gain of 6 but only gave me negative values. esphome: name: pool platform: ESP32 board: nod...

No worries! Responded

it's to Oetsch

Hi had constructive discussions on how to use this pH sensors in another forum. Why are you using level shifters? the pcb of the ph Sensor has everthing onboard. You have two trimmer for calibration. One is used to shift the voltage in the positive area with a miminum of 0V. By default this ph sens...

Thank you!
All of this is still a work in progress so all can change

So wire the gnd together so it only used 1 pin on the ESP?

And the two pull up resistors could be exchanged by a level converter ? Have some lying around

Thanks! Wiring seems fine ?

some other forums recommended it since it would improve accuracy, but i don't see where this would be improved tho.

indeed true, with a voltage divider. But the ads1115 should be doing fine since it accepts 5V. question is if a I2C level converter is recommended/needed.

The PH sensor would output 5V. some said that it doesn't matter for the digital pins sice the ads1115 will convert it to a digital signal.

Would need to check if it's 5v indeed. according to documentation, it should... I will power it with a 5v1a adapter .

should this diagram be considered to be working or would i need a level converter?

Hi all,

I searched to get the differences between the testing channels but haven't found any summary /info.

I would like to use the Blynk controller for example and maybe some other new features.

The board has screws for calibration. Should i do this in espeasy or should i do it with the 2 screws (please a bit of explenation on the 2 screws.)

Thanks man, great guide!

Hi all, thank you for this project! I have recently bought this ph sensor with the included bnc board : https://nl.aliexpress.com/item/1005001612930856.html?spm=a2g0s.9042311.0.0.63914c4duSIvfn Also an ads1115 to connect it to my esp8266 without any issues. It should read fine. I have read that it s...

Yes, it worked!

Just needed to remove the '%' in my syntax.

/update?api_key=xxxx&field1=[zwijver#temperature]&field2=[zwijver#temperature] with zwijver being task and temperature the value.

Hi, thanks!
It isn't a Task at the moment, it's only a device.

Yeah wrapped in the %. But what exactly is thé label i need to wrap in. At thé moment i only have one sensor, thé Dallas ds18b20

hmm that doesn't seem like somthing i can put in the http request.

I'm very new to this. i would like that thingspeak can just copy 1 field to another, but not possible

I get values on my thingspeak channel, it works with a static value. What is the variable for the output of the ds18b20? or how can i get it

update?api_key=xxx&field1=%device1%&field2=%device1%

I need to get the correct piece for the device

aha that can come in handy. in my espeasy setup, i don't see rules...

Will get the advance http, works better

Sure! I think, at the moment it is something like : https://api.thingspeak.com/update?api_key=xxxxxxxx&field1=0 and i would like to have a second one so i could display daily averages without the need of creating a new channel and writing and reading from it. https://api.thingspeak.com/update?ap...

Hi all,
Is there a possibility to edit the link that espeasy generates to update a field, i would like that multiple fields get updated. So i can make a plot of all temperatures and a daily average.
