# Known Issues
Issues have been reported with data; these vary by firmware version. Newer firmware may resolve these or introduce new issues.
## Production & Consumption data
| data | envoy <br> type [^1] | issue | in firmware |
| ------------------- | -------------------- | ---------------------------------------- | ----------- |
| whToday | Mtr | late reset some time after midnight | |
| | | reset to non-zero value | |
| | | sudden value step changes | |
| whLastSevenDays | Mtr | sudden value step changes | |
| watt_hours_lifetime | NoCT | reset to zero when reaching 1.19 MWh | \<8.x |
| | Std | 1.19 MWh value stepdown | |
| all | NoCT | stalled values in V1 Production Endpoint | >= 8.2.4264 |
[^1]: Std: Envoy standard (not metered). Mtr: Envoy metered. NoCT: Envoy metered without installed and configured CTs.
## Inverter device data
The [inverter device data](endpoint_json.md#ivppdmdevice_data) includes a `deviceDataLimit` that appears to be fixed at 50. If more inverters are installed, only data for the first `deviceDataLimit` inverters is included, resulting in missing inverter data. When the reported `deviceCount` is greater than or equal to `deviceDataLimit`, data falls back to [/api/v1/production/inverters](endpoint_json.md#apiv1productioninverters) to avoid data loss; device detail data will then be unavailable for all inverters.
