I have set up a ModbusE interface to read from a Powerstandards Pqube3 power measurement unit. I am able to read data from the unit, however, most data are only read once. It never updates after the initial read. I cannot get it to update in Poindexter or in with the PI interface.
When I monitor the device with the Pqube modbus client, it updates continuously. Any ideas what could be the reason for this?
Also, I have problems with compression. Even if I have compression on, the interface still archives values according to my scanrate, which is set to 1 second. How can I avoid this?
