Hello @sbr,
the IOs of the Neuron are not connected to the GPIOs. Instead, they are accessible via local ModbusTCP server (you can see the Modbus Registers Map)

Or better yet, check the official Neuron plugin for Codesys: https://store.codesys.com/unipi-neuron-for-codesys-sl.html?___store=en&___from_store=default

Hello @zorro_66,
the problem with 1-Wire bus is, that there are no guarantees about its functionality. You may have 10 sensors on 100m bus working just fine and you can have 5 sensors on 20m that will not work at all.

The general guidelines are:

1. Avoid stub and star topology (e.g. use our 4 wire sensors)
2. Use shielded cable and don't lay the cable along the 230V power lines

For more detailed information, try reading this paper from Maxim: https://www.maximintegrated.com/en/app-notes/index.mvp/id/148

Hi @martijn-hemeryck,
We changed the repository's name to unipi-python-lighting and it resides here: https://git.unipi.technology/UniPi/unipi-python-lighting

Hello @tgurecky,
in this case, the only way is the ST. Do you need some help with that?

Hello @zorro_66 , the restart of the 1-Wire bus is not available on the UniPi 1.1.

Hi @juntiedt,
there is a M103 with 8 relays.

Hello @origami,
the UniPi 1.1 doesn't need any firmware. To use the newest set of tools, do full update & upgrade of the operating system.

Best regards,
Martin

Hello @tgurecky,
the "Multi In Real" should do what you are looking for.

Hello @somapa,
the first thing is to configure the Siemens PLC as the ModbusTCP slave. Unfortunately we don't have any direct experience with it, so you have to look for help somewhere else. But you can verify the settings with e.g. qModMaster.

The second step is to configure generic Modbus slave device in Mervis and we have a tutorial for that: https://kb.unipi.technology/en:sw:01-mervis:connecting-to-modbus-slave-device-hidden

If, in any case, you wouldn't be able to set the Siemens as ModbusTCP slave, you can set the Mervis as ModbusTCP slave and let the Siemens update the registers. You can read more about how to set the Mervis as ModbusTCP slave here: https://kb.unipi.technology/en:sw:01-mervis:setting-modbus-server-hidden

Hello @christian,
the websocket interface sends only values which has changed. To request all current values, send this command at any time:

{"cmd": "all"}
