🐈‍⬛🐈‍⬛ iwait, ifeed, istream while iwatch...

Opinionated cat feeder, optimised for RPi Zero W and other materials on hand.

iwait

trigger dispensation on a cron schedule

• IWAIT_MEAL_SCHEDULES controls cron schedule (e.g. 21,2,6,*,*,* to dispense @06:02:15)
• IWAIT_SNACK_SCHEDULES controls cron (snack) schedules
• TZ sets timezone (e.g. US/Pacific)
• IWAIT_SLACK_{WEBHOOK_URL.ERRORS_ONLY} controls Slack integration parameters

ifeed

dispense on GPIO (physical push buttons) or USR{1,2} Linux signals

• IFEED_{MEAL,SNACK}_RUNSECS controls dispensation duration in seconds on USR{1,2} events
• IFEED_BUTTON{1,2}_GPIO sets button pins (physical board pin numbering scheme
• IFEED_PWM{1,2}_GPIO sets servo motor pins
• IFEED_HEARTBEAT_URL send an empty HTTP request to reset alert trigger
• IFEED_ALERT_RESET_SIGNALS reset trigger on specific signals only

istream

stream video to RTMP sink (poorly on RPi Zero W) with raspivid or serve timelapse stills (better) with raspistill and nweb

• ISTREAM_RTMP_URL controls where raspivid streams to (e.g. YouTube, Restream, etc.); or
• ISTREAM_STILL image name for raspistill timelapse (e.g. somewhere on tmpfs ideally)
• ISTREAM_VIDEO_{H264_PROFILE,WIDTH,HEIGHT,FRAMERATE,BITRATE,KEYFRAME} sets video parameters
• ISTREAM_AUDIO_SAMPLE_RATE (ffmpeg) sets empty audio stream bitrate
• ISTREAM_IMAGE_{WIDTH,HEIGHT,ROTATE,ANNOTATE} still image parameters

iwatch

serve a HTTP redirect or static HTML with netcat as well as /health endpoint

• IWATCH_STATIC_HTML controls static HTML content (e.g. YouTube iframe/embed)
• IWATCH_REDIRECT_URL controls redirect URL if no static HTML specified
