pwrcell.generac.com API

All under https://pwrcell.generac.com

• Get list of devices
  • /{profileId}.json
  • profileId comes down in the initial html response
  • ex: {"dvcs":[{"s":"000101000004","n":"Pika PVLink ","st":8208,"t":"PV Module","p":614,"et":272466}, ... ]}
• Get power (watts) per time period
  • /power/{deviceId}/{endTimeLocalTzSecs}/{lookbackRangeSecs}.json
    • endTimeLocalTzSecs can be special value now
    • lookbackRangeSecs can be special value all
      • I'm unsure how far back all goes
  • Period is 3600s (1hr) unless lookbackRangeSecs is less than 36hr then period is 60s (1m) (assuming based on JS code)
  • ex: TODO
• Get energy (used/stored/created?) in (watt hours?) per time period
  • /charge/{deviceId}/{endTimeLocalTzSecs}/{lookbackRangeSecs}.json
    • endTimeLocalTzSecs can be special value now
    • lookbackRangeSecs can be special value all
      • I'm unsure how far back all goes
  • Period is 3600s (1hr), doesn't appear to provide high-resolution view even with short lookbackRangeSecs
  • ex: TODO
• Get battery charge (watt hours) per time period
  • /charge/{deviceId}/{endTimeLocalTzSecs}/{lookbackRangeSecs}.json
    • endTimeLocalTzSecs can be special value now
    • lookbackRangeSecs can be special value all
      • I'm unsure how far back all goes
  • Only valid for battery device
  • Period is 3600s (1hr) unless lookbackRangeSecs is less than 36hr then period is 60s (1m) (assuming based on JS code)

• A valid _PikaUserProfiles_session cookie is required to submit the login form
• Once logged in only the remember_token appears to actually be needed
