When state is unavailable the NetDaemon treat is as Null state.

[helto4real]

Breaking change

It can be breaking if you rely on:

if (entity.State == "unavailable") ...

after:

if (entity.State is null) ...

Proposed change

The changes the behavior for entity states that are unavailable. Any state that is unavailable is set to null value. You now do not have to check for unavailable in the scenarios you expect state to be a number as an example.

this code breaks now but will be fine with this PR since state is null when unavailable value to the state.

        public async override Task InitializeAsync() => Entity("sensor.hacs")
                .WhenStateChange((n, o) =>
                    o?.State != n?.State && n?.State > 0)
                        .Call(async (entityId, newState, oldState) =>
                        {
                            var serviceDataTitle = "Updates pending in HACS";
                            var serviceDataMessage = "There are updates pending in [HACS](/hacs)\n\n";


                            List<object> repositories = newState?.Attribute?.repositories || new List<object>();
                            foreach (IDictionary<string, object?> item in repositories)
                            {
                                serviceDataMessage += $"- {item?["display_name"].ToString()}\n";
                            }

                            await CallService("persistent_notification", "create", new
                            {
                                title = serviceDataTitle,
                                message = serviceDataMessage
                            }, true);
                        }).Execute();
