### Lifetime energy production decreases by 1.2 MWh
Envoy Standard (not Metered), running firmware 8.2.4264, reportedly decreases the **Lifetime energy production** value by 1.2 MWh at irregular times. The current hypothesis is that the step change occurs when one of the inverters exceeds an internal lifetime joules counter of 32 bit, which is 1.19 MWh, and resets to zero. This leads to a decrease of 1.2 MWh in the aggregated value for all inverters. It's not clear if this also happens for the metered Envoy.
The envoy, as of firmware 8.2.4264, reportedly decreases the **Lifetime energy production** value by 1.2 MWh at irregular times. The current hypothesis is that the step change occurs when one of the inverters exceeds an internal lifetime joules counter of 32 bit, which is 1.19 MWh, and resets to zero. This leads to a decrease of 1.2 MWh in the aggregated value for all inverters.

To correct for this issue, a sensor [blueprint template](/integrations/template/#using-blueprints) named [`Correct Envoy lifetime production energy`](https://community.home-assistant.io/t/correct-envoy-lifetime-production-energy/942918/1) is available in the community blueprints exchange.
Import the blueprint using the **import blueprint to** button. This will install the blueprint as `/config/blueprints/template/marcelhoogantink/correct_envoy_lifetime_production_energy.yaml`. Use the templates shown in the blueprint exchange to implement an entity with a corrected lifetime value.
### Missing inverter data
If you are not seeing all your installed [inverters](#sensor-entities), and you have more than 49 inverters installed, and you are running HA 2025.7, 2025.7.1, or 2025.7.2, then upgrade HA to 2025.7.3 or newer. Due to a limitation in the Envoy firmware. Only the inverter details for 49 inverters are available. In the mentioned releases, any more inverters got dropped. The 2025.7.3 version fixed this by only using the inverter base data, which does not have this limitation.
