I have a Particle Boron and want it turned into a small proof-of-concept that watches two reed switches and a single split-core current transformer. Whenever either switch changes state or the CT reports a reading outside user-defined limits, the Boron should push an SMS straight to my phone. Please build the firmware, wire the sensors, and set up the cellular messaging so the text includes three key pieces of information whenever a condition is met: the live state of each reed switch, the measured current, and a timestamp noting when the limit was crossed. I also need your guidance in deciding the actual thresholds for both the switches and the current transformer, so factor parameter-setting into the workflow. A concise wiring diagram, commented source code ready for Device OS, ...

I need a mobile PBX application that lets my team place and receive internal calls entirely over our local Wi-Fi network. The app must run smoothly on both iOS and Android and register 51-200 extensions without relying on cellular voice or external trunks. Core functions I must see on day one: • Call forwarding, including unconditional, busy, and no-answer rules • Visual voicemail that stores messages locally and syncs with the PBX I have no immediate need for call recording, yet I prefer a codebase that leaves room to add it later. Whether you build the PBX side (Asterisk, FreePBX, 3CX, etc.) from scratch or integrate with an existing server, the result has to deliver reliable SIP registration, push notifications for incoming calls, TLS/SRTP security, and a clean user...

The machinery is already fitted with basic IoT-ready sensors; what is missing is the cloud-to-device bridge and a clean user interface where I can watch throughput, temperature, and fault codes in real time. Here is the flow I have in mind: • Edge device pushes sensor readings via cellular data to a secure backend (MQTT or HTTPS—use what you are most comfortable with). • Backend stores, normalises, and exposes that data through an API. • A web or mobile dashboard pulls the feed and displays key performance metrics with alerts when values drift outside preset thresholds. That monitoring dashboard is the first milestone and the only compuls...

I’m working on a project with the AVR-IoT Cellular Mini (Sequans Monarch 2 modem), where I modified the Arduino-based firmware myself to periodically transmit GPS latitude and longitude data to my backend (BE) over HTTPS. The objective is to send GPS data (latitude, longitude, and timestamp) to a REST API endpoint at a defined interval and confirm that the data is successfully received and visible on the backend. At the moment, I’m blocked by a TLS issue while attempting to configure the CA certificate for HTTPS. When I try to add the root CA certificate (ISRG Root X1 – Let’s Encrypt) to the device/modem, I get an error that says: “CA certificate input too long” Because of this issue: • The TLS handshake fails. • The HTTPS request ...
