Hi Sara,

Just wanted to say thank you for your help and kind support, now everything is working as expected and just need to calibrate the Y4000.

Attached is a screenshot about the final results, I needed to twerk the delay time a little bit and make sure grounding overall is respected, but other than that everything worked  fine.

Thanks again.

Hi Sara,

Again thank you for your help, I am supplying the Y4000 from a dedicated power supply and I have done all the code instruction you gave earlier.

The code is working. However, the sensor is not responding back as you can see in the attached picture. I thought it might be a grounding issue so I have connected the grounding from the sensor with the MKR485 grounding, nothing have changed. Tried to change the modbusAddress = 0x03 into 0x01 as a try, also nothing changed.

If anything comes to your mind on what can be the issue please let me know.

Hi Sara,

Thank you very much for your help, I actually have a Y4000 and I have managed to communicate to it and use it connected to a PC, I am trying to monitor a near river.

I tried to work as you have written earlier, the problem is it looks like I am overwriting the serial connection to the PC, so the second the code uploads the USB connection is lost and the serial monitor is not working.

I am using the modified code by Anthony Aufdenkampe based on the GetValues.ino and I wonder if you can have a look for any tips on what might be the issue, thank you very much in advance.

Hi @sara,

I am trying to connect a y4000 to my arduino using an mkr 485 sheild (RS485) for hardware serial port  using your arduino library for y4000, till now with no luck.

I suspect it is because of the “AltSoftSerial” creating software port while I am using a hardware one, but I am not sure how to modify this.

Can you please help with some tips or thoughts?
