not really sure what combination of nodes to use for this so i'm hoping someone can point me in the right direction. i'd like to trigger a flow at 6am starting the next day after any reboot (or same day if reboot before 6am) and then repeat every 3 days until the next reboot. sorry if i'm overlooking something obvious. any ideas?

Try the inject node set to specific time, 6am. Followed by a delay node, set to rate limit one message per 3 days, and discard intermediate messages.
e.g.
```auto
[{"id":"47c4dc2f.7863fc","type":"inject","z":"8d22ae29.7df6d","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"00 12 * * *","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":160,"y":2660,"wires":[["136d1e93.688f71"]]},{"id":"136d1e93.688f71","type":"delay","z":"8d22ae29.7df6d","name":"","pauseType":"rate","timeout":"5","timeoutUnits":"seconds","rate":"1","nbRateUnits":"3","rateUnits":"day","randomFirst":"1","randomLast":"5","randomUnits":"seconds","drop":true,"x":350,"y":2660,"wires":[[]]}]
```

If you need a second way the bigtimer node will also do what you need
