My board is Z-Uno2 Rev. 6. I notice that the firmware seems to be for Rev. 7 now. The picture of the board in the documentation is a little different from my board as well - no socket for a battery connection, perhaps? Where can I find Rev. 6 firmware?

I suspect I am forgetting something very simple. Z-Uno 2 Rev. 6, connected to COM 9, all seems fine. Compile and download Blink example sketch, no errors. Red LED flashing rapidly, no errors shown in Serial monitor (no other serial communication in the sketch in any case). Bad board, or something in...

Good information, Ian - thanks! I think my network is pretty busy as it is (almost 50 devices, some of which are programmatically controlled already), so I think I might be better off using a WiFi device (like a WeMos D1 Mini or an Arduino Nano ESP32). I won't be using the flow rate for control - at...

I would like to use a Z-Uno for controlling my garden irrigation system - three 24 VAC solenoid valves. Wiring to interposing relays is not difficult; neither is creating programming so that the control box can have a "Manual/Automatic" switch so we can turn on a valve when working in the ...

Nope. Doesn't work that way either. Any suggestions?

Do I have to uninstall Z-Uno2 3.0.10 before I install the Beta version 3.0.12? I ask because the installation of Z-Uno2(Beta) in Arduino IDE 2.1.1 fails repeatedly.

I had to reinstall all my software on my PC due to a re-installation of Windows. Trying to get the Arduino IDE up and running again so I can go back to work on my devices, and I find I can't install the Z-Uno2 board file in IDE version 2.3.2 or 1.8.19. Added the URL to the Additional Boards Manager ...

Depending on the pressure range you wish to measure, there are a number of devices available that provide a 0.5V - 4.5 VDC analog signal for water pressure. I found a couple from DigiKey: a) Seeed Technology part number 1597-1515-ND for about $20 CDN that will measure 0-1200 kPa, and b) Honeywell Se...

Am I reading this correctly, then - there is NO way for a user to add or modify the sensor types or scales used in the Zuno?

Thank you for the information. In my case, I wanted not only the rain rate (mm per hour), but the accumulated rainfall in mm. The total rainfall in a given hour is in fact more useful that a rain rate, in that I can use it to decide if the garden has had enough rain in the past 8 hours, or do I need...
