Hello,
we have Teltonika TRB140. Is it possible to write values to modbus slave from Azure IoT Hub and how is this done using MQTT? There are manuals for reading values from modbus slave to IoT Hub but little knowledge about writing values to device (and from there to modbus slave).

Implemented your required functionality from AWS-IoT. However, running openwrt on RUT955, connected via USB-RS485 to ModBus and multiple slaves. WAN via LTE, Wifi or LAN-cable.
