Elgato Eve HomeKit Services & Characteristics

A work in progress collection of proprietary and as of yet undocumented HomeKit characteristics and their UUIDs used by Elgato Eve.

This list is not including all Eve accessories available and some services and characteristics still make no sense to me. If you have anything to contribute, please leave a comment. There is no guarantee that the information listed below is correct.

Notes

The last two may be a cache of measurements that are polled by the Eve app when the accessory is in range.

E863F117-079E-48FF-8F27-9C2605A29F52

Array of logs with each entry having x bytes as determined by Byte 1. The following is what I think I learned about logs with 20 bytes. I have already seen 21 bytes but haven't taken a look at those yet:

  • Byte 1: Length (i.e. 14 for 20 Bytes)
  • Bytes 2 & 3: Counter
  • Bytes 4 & 5: ??? (always 0x00 or maybe an extension of the counter?)
  • Bytes 6 & 7: Seconds since ???
  • Bytes 8 & 9: ???
  • Byte 10: ??? (always 0x1f?)
  • Bytes 11 & 12: Watt (W)(see E863F10D-079E-48FF-8F27-9C2605A29F52)
  • Bytes 13 & 14: Volt-Ampere (VA) (see E863F110-079E-48FF-8F27-9C2605A29F52)
  • Bytes 15 & 16: Volt (V) (see E863F10A-079E-48FF-8F27-9C2605A29F52)
  • Bytes 17 & 18: Ampere (A) (see E863F126-079E-48FF-8F27-9C2605A29F52)
  • Bytes 19 & 20: ??? (might correspond to E863F10E-079E-48FF-8F27-9C2605A29F52)

Bytes 6 to 9 look like some kind of timestamp. The format is not clear but from the limited dataset available to me up to now it seems that they are offsets from an initial timestamp, most likely the original installation date. Bytes 8 and 9 could thus be something like "days since installation".

This characteristic seems to only return a maximum of 11 log entries and I have no clear idea on how to scroll back in time. Maybe that's what either E863F11C-079E-48FF-8F27-9C2605A29F52 or E863F121-079E-48FF-8F27-9C2605A29F52 is for: You write a value to one of the characteristics and get a different range from the logs. Just a wild guess.

Has anyone been able to render out and energy history from a real eve power device, or get a humidity / temp graph from the devices?

i'm interrested to know too :)

Can Home Assistant automate and query these commands?
