  1. Réponses à Freezer at -12.5 C shows up as 65411 after going through my Modbus slave

    The raw -= 65536 fix works, Hermetry shows -12.5 now and the chart doesn't jump to 6000 anymore. Yesterday's 6541 points are still sitting…

  2. Ouverts Freezer at -12.5 C shows up as 65411 after going through my Modbus slave

    Student, first Modbus project. Arduino Mega reads a freezer probe and acts as a Modbus RTU slave (ModbusRTUSlave library). I store the temperature times…

  3. Réponses à Gateway datasheet says the 24 V digital inputs draw a ‘current load’. What does that mean for my sensors?

    That explains it, thanks Ciaran. We swapped the NPN proxes for PNP ones (the lab had some), the door and float switch go from…

  4. Réponses à Gateway datasheet says the 24 V digital inputs draw a ‘current load’. What does that mean for my sensors?

    We only need on/off states, no counting. Good to know though.

  5. Ouverts Gateway datasheet says the 24 V digital inputs draw a ‘current load’. What does that mean for my sensors?

    Student again. For a lab rig we have a gateway with 4 digital inputs that we want to use for a door contact, a…

  6. Réponses à ESP32 connects in setup() but client.connected() is false a few seconds later in loop()

    Fixed, but it was two things! Log tab showed keepalive_timeout AND "Taken over by a new session". My first breadboard prototype was still plugged…

  7. Ouverts ESP32 connects in setup() but client.connected() is false a few seconds later in loop()

    Uni lab, ESP32 DevKit, PubSubClient, WiFiClientSecure. In setup() I connect to Wi-Fi and to Hermetry, it prints "MQTT connected", and the first reading arrives.…

  8. Réponses à Request: let rules weight a model’s prediction by its confidence (feed-forward setpoints)

    Got it working on the lab furnace with clark.c's script and a 10-minute expiry on the Pi side. My first deploy didn't fire because…
