TKB Home TZ88
It appears that when adding the new TKB Home TZ88 (On/Off Meter), the Zipato web app can detect that it is a meter but is unable to detect any values. Looking at the events there appears to be a single value named VALUE1 being reported every few seconds. This value is shown in the android app as the meter value. Let me know if there is any further information I can provide that might make supporting this device possible.
