Wemos D1 Mini Presence cube

thingiverse

I wanted to use a D1 mini as all the presence cubes on here were using NodeMCUs and were huge, ended up making 4-5 different prototypes before I settled on a design that should fit most USB cables. I used a 8 LED ring WS2812 from Aliexpress https://www.aliexpress.com/item/32835427711.html Top was printed in clear \ translucent filament Bottom can be printed in any colour you like Inside was printed in clear also just to make it "invisible". I use https://github.com/isaacrlevin/PresenceLight (also avaliable in Microsoft Store) to publish status changes to WLED via API Examples using Custom API : Avaliable - GET - http://x.y.z.o/win&R=0&G=255&B=0 Busy - GET - http://x.y.z.o/win&R=0&G=255&B=0 Also possible to integrate in Home assistant and let the light control be done via esphome. Example esphome config : <code> esphome: name: teamskube platform: ESP8266 board: d1_mini on_boot: then: \- light.turn_off: teamscube wifi: ssid: "ssid" password: "password" ap: ssid: "Teams-Kube Fallback Hotspot" password: "zTa3IHiNbIG8" captive_portal: logger: api: ota: light: \- platform: neopixelbus type: GRB pin: GPIO3 num_leds: 8 variant: WS2812 name: "teamscube" id: "teamscube" </code> with HA automations using webhooks : <code> \- alias: 'Teams away' trigger: platform: webhook webhook_id: hadoken action: service: light.turn_on data: entity_id: light.teamscube rgb_color: [255,255,0]</code>
