Samsung energy consumption has increased during warmer weather
A recent change to the data we receive from some Samsung heat pumps means that the energy and cost data is being over-reported
During long periods where both the heating and hot water is inactive, the heat pump continues to report that electricity is being consumed - even when it is logically not.
Unfortunately, this isn't something we can fix easily on our side. We will continue to monitor the situation/
Heat pump temperature data lags slightly behind the manufacturer controller/app
The maximum delay should be 5 minutes for most brands. For some (e.g. Samsung, it is 2 minutes. This doesn't affect Havenwise operation, as it is not an on/off controller.
For room temperatures provided by a Shelly device, latency is about a minute when powered by cable. When powered by batteries, it updates whenever the Shelly changes by more than 0.5C.
Vaillant onboarding: Gateway serial number not recognised, when it is correct.
Usually this is due to having had a PCB replacement at some point. These heat pumps have an invalid serial number which is mostly 0s. This can be fixed by emailing Vaillant directly - they are quite responsive to this issue.
