-
Tasmota
Alternative firmware for ESP8266 and ESP32 based devices with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at
Project mention: Printing emails based on Message Filters, does not seem possible | /r/Thunderbird | 2023-12-02All of my office devices are connected to Sonoff S31 smart plugs, flashed with Tasmota on their own locked-down VLAN, and can be controlled via voice, Alexa, Tasker automation on my Android, NFC tags at my office door and various scripts triggered via my StreamDeck (on Linux). This all works fantastic, and I can turn on or off my devices, including my printer, when I start or end my day at work.
-
WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
-
I've found myself at this webpage multiple times while trying to minimize the complexity of APIs in my C projects.
My conclusion for now is that C coroutines are something to be left to the implementer. For example: Mongoose (https://github.com/cesanta/mongoose) uses event callbacks to deal with asynchronousness. It is much more pleasant to wrap a library like this in whatever thread/task primitives your system has rather than try to integrate the mythical cross-platform c couroutine.

Project mention: Passive esp8266 project when you have an extra one laying around? | /r/esp8266 | 2023-05-21
Other ideas: - Setting up a Wifi sniffer to detect which devices are around - Make it an MQTT broker: https://iotbyhvm.ooo/esp8266-mqtt-broker/ - Making it a Remote serial device: https://github.com/jeelabs/esp-link
