Dear All,

I thought that maybe the best way to share this is to have a showcase project that you can clone and extend or rewrite for your own purposes. That's why answering took a little while, sorry.

Hi Steelhead,

We are happy users of the Unipi xG18 for 1-wire temperature measurement.

Dear mrau, What would you like to know? We don't use the gateway modules, but we map the RS485 UART into containers for Modbus applications. Besides that we do use a mix of AIO and MIO modules. Then we have revpipyload write all data into an MQTT bus as well as receive output values via MQTT. Everyt...

Dear mrau, We also use mostly Python 3, but have opted to run all our software in Docker containers. This has the added benefit of version locking all Python and system library dependencies. It also means we don't depend on things being a Revolution Pi as much (we have a mix of Revolution Pi, Unipi,...

Dear Kunbus, What is the maximum baud rate that we can run the RS485 port on the Revolution Pi Connect+? Use-case is querying a load cell at the highest possible data rate we can achieve. How is the RS485 port connected inside the Revolution Pi? Custom hardware, or one of the Raspberry Pi UARTs? I s...

Dear Dirk,

What about if I wanted to do the same from Python?

Dear All, A while ago we had a strange outage, where the Revolution Pi would no longer have network connectivity, but the control systems would still work properly. Just the HMI and data logging were no longer accessible and we could not VPN into the system. After some digging (and a bit of luck) we...

Dear Mani, I cannot help you with the problem much, but I can give you some background. It's a bit of a ramble, sorry. :) The definition of UNIX load is a bit hazy, but it does not reflect CPU load in the way that you assume in your post. The original intention being to say something about things li...

Dear Jemmima, The instructions I posed are for Buster. What OS release are you on, please? $ cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID...

On the Revolution Pi, when upgrading the packages raspberrypi-kernel-headers and/or raspberrypi-kernel, WireGuard’s kernel module gets disabled. You will no longer have remote access (!) After installing or upgrading raspberrypi-kernel-headers or raspberrypi-kernel, always reinstall the WireGuard ke...
