      I still have the same issue for my sites too.

      Also TSA only seems to show battery voltage and Mayfly board temperature.

        Thanks for the info Neil.  Glad to know it’s not something I am doing wrong!

          Thanks Neil.

          I contacted the NZ branch of SApply and they have around 40 in stock, but that’s it for a while.  It sounds like it’s related to the issues that are plaguing the semiconductor supply chain at the moment.

            I had a lightbulb moment today that seems to have fixed my problem.  I switched the 3.3v jumper to 5v.  Success!!  I guess it was brown-out.

              I have switched my pin for the HYDROS 21 CTD from D7 to D11, but I seem to be having the same issue.  It’s worth noting that I don’t get -9999 values when plugged into my computer.  Could it have something to do with power?

              My code is below.

                Hi Shannon,

                Yes I am on D7 for the CTD. I am using the default pins for the mayfly modbus wing (https://github.com/EnviroDIY/Mayfly-Modbus-Wing/tree/master/Modbus-Mayfly_WingShield):

                  Hi Matt,

                  This is an old thread but I have recently purchased ten Y511-A sensors from Yosemitech.

                  My contact is called Zoe “sunxian@yosemitech.com”.

                    Thanks Anthony! I’m feeling a lot more comfortable about Yosemitech sensors now that I have a test unit in my hands. I can’t wait to get them out in the field.

                      Also, for anyone who is interested.  My solution to testing multiple TTL-RS485 adapters with one rig can be seen in the attached photo.

                        Hi @aufdenkampe,

                        That’s really good news.  Yes I was reading through some historical issues on git-hub about problems with the Polou step-up module and inability to set brush intervals. My 511-A seems to be functioning well so I’m assuming the Polou step-up issue is also solved.

                        One quick question, In your view, is the 511-A worth the extra money over the 510-B?

                        Edit: I also need to thank you for the 120 ohm resistor trick.  So far I have tested four TTL-RS485 adapters and all of them required a 120 ohm resistor to function properly.  They all work with that slight mod though!

                        James
