    • RE: 1-wire sensors and Mervis - need to replicate configuration easely

      i spotted that linux kernel module does not have this limitation in functionality. From the first boot i can access to the sensors info without any configuration using the meta filesystem /sys/bus/w1

      Easy to explain: 1 UNIPI S105 and 6 temperature sensors on 1-wire bus.
      All is ok. To configure from scratch i have to add-channel, select Onewire, right click on channel_0, detect sensor, select all 6 detected sensors, map each temperature variable to a modbus register and BUM, it's working.

      What if i have to make hundreds of this configuration?
      Simply it's not functional, becouse even if i save the Mervis configuration, (as far as i know and i tried) it does not work on new controller because of the uID of 1-WIRE, every sensor has a different ID so MERVIS configuration has to be updated every time, booting the device with attacched new sensors, scan the bus, attach variables to modbus registers etc etc...

      Is there a way to have a mervis configuration that work out of the box?

    • RE: Hardware Request: Hirose U.FL connector on board

      it's clear that violates it. That's why i'm submitting an hardware feature request. It's a suggestion becouse others edge device has this feature.
      Thanks.

    • Hardware Request: Hirose U.FL connector on board

      instead of adding hardware wireless nic to the board it's preferrable to have an external antenna connector. Normally we have the neuron close inside metal cabinets and the SNR degrades vertically.

      our failback now is to use a tplink nano router and put it external to the cabinat, but it would be preferrable an antenna.

      thanks
