I want to reconfigure my home network so that two routers work together: the first handles all personal devices, the second becomes an isolated guest network for visitors. Coverage is not the issue—security is. The guest network must be password-protected, placed on its own subnet or VLAN, denied access to the main LAN, and have basic monitoring or logging in place so I can quickly spot unusual traffic. Your task is to walk me through, or remotely complete, the full configuration: • Flash or update firmware on both routers if needed (OpenWrt, DD-WRT, or the manufacturer’s latest stock OS—whichever best supports VLAN and traffic monitoring). • Set up strong WPA2/WPA3 credentials and disable WPS on both units. • Create the guest SSID on the second route...

I have built a website for charity which needs to notifications to members. I am looking for an alternative to bulk email and WhatsApp. I am looking for an android app which can receive alerts, for example via JSON, then sends push notifications to members. If a member is offline i.e. turned off their phone data or WiFi, they should get the notification when they come online. The android app may either have just a single screen opening the website or it may run as an invisible background service. You are NOT required to replicate an android version of the entire website, just notifications only. I need an API endpoint. The notification goes to a member or group of members who currently login to the website with an email and password so each member has a unique member number. The...

I already have a custom board built around an ESP32-D, the accompanying PlatformIO project, and fully working low-level drivers for Wi-Fi, MQTT, GPIO and storage. What I still need is the high-level logic that ties everything together so the device behaves like an intelligent Wi-Fi switch. Here is what the finished sketch must do: • Subscribe to a dedicated MQTT topic and parse the JSON commands coming from my mobile app. • Execute each command immediately, switching the relay output on or off and publishing an acknowledgement with a timestamp. • Monitor the on-board push-button; every manual activation should be time-stamped, stored locally, and later pushed to the same MQTT broker so that no event is ever lost if the connection drops. • Run both daily and week...

I have an ESP32 Basic Core IoT Development Kit V2.7 installed in my truck and need firmware that will warn me whenever the Starlink router stays powered after I switch the ignition off. The sketch should watch a dedicated ignition-sense pin: while the line is high the unit does nothing special, but as soon as it goes low it must keep polling the Wi-Fi connection status in code. If the ESP32 is still associated with any network after a user configurable amount of time, an on-board LED must begin to flash, screen starts flashing and the internal speaker must chirp in tandem until the Wi-Fi link drops or the ignition is restored. I would like a simple LCD screen interface on the kit’s I²C display that shows real-time states (“Ignition ON / OFF”, “Wi-Fi CONNECT...
