    Hi, I need to program the LILYgo 7000G board to communicate via MQTT via LTE and wifi. It is also required to read the GPS position. Regarding the power part, it is necessary that the board goes into deep sleep consuming in general less than 50 ua/hour. To achieve that it should be possible to turn off the SIM7000G via software through the ESP32 and put the ESP32 into deep sleep. It would be necessary to see the rest of the electronic components and their power consumption.

    We are developing a PoC for an IoT solution using state of the art hardware. An important deliverable is to configure the PoC hardware correctly so it communicates efficiently with the cloud solution and between devices. The cloud solution is an AWS-based MQTT broker that connects to InfluxDB and/or Azure IoT, but this may be re-developed to connect directly via MQTT using Azure IoT DPS and Azure IoT Hub. There will be two types of hardware in general. Some LTE/NB-IoT gateway autonomous devices and some BLE devices that will need gateway devices to connect to the cloud. Units must be configured to send sensor data to the cloud solution in the correct frequency. High-level tasks includes, but are not limited to: 1) Development of new and/or changes of existing firmw...

    I created a Code for a Wallbox, so that Hotel Guests are able to use their Hotel Room Cards to start a charging process. The Code basically checks the validation of the Room Card, reads the Room Number of the Card, and transmits Room Number and the authorization to the MQTT Server. The Charging Station does the rest and sends an Email at the End. The Code works, but I have some hickups with collecting the mqtt Data of the current charging Rate and total Amount. Now I thought if it would be possible to use it with Tasmota, so I would be able to edit the Script from Remote, and don't have to flash the pcb onsite if changes are needed.
