Script description

Shows what Appliance Monitor (Homebridge) measures at a coffee machine's smart plug, over MQTT.

  • HEATING while it warms up, until the first coffee once it is warm: how far, as a bar like the one AWTRIX NG boots with or as a percentage, taking turns with how long until it is preheated
  • ON (time since switch-on) and a red HEATED once it is warm, alternating every 3 seconds
  • OFF: a countdown to when your automation switches it off, yellow in the last minute; standing still at its full time while the machine is in use
  • SHOT: while the pump runs, the timer takes over the display and counts every second
  • Afterwards SHOT or RINSE with the measured time, in green; a run shorter than a set time (15 s by default) is a RINSE as soon as the pump stops

On a TC002 (52×16) a 16×16 cup and two lines; on a TC001 (32×8) an 8×8 cup and one line, the two taking turns.

Needs Appliance Monitor 1.16 or later with MQTT on, the clock on the same broker, and a few phases set up on the coffee machine, and optionally two MQTT messages for the plugin's exact shot count. Every topic, threshold and colour is a setting.

Optional: a temperature sensor on the machine (e.g. via deconz-mqtt) for an exact HEATED. Without one, a machine switched on cold counts as preheated after a set time (30 minutes by default), as a heat exchanger's group takes far longer than its boiler.
