The MQTT ONLINE status does not work as expected #112

Open gitpower2017 opened 3 years ago

gitpower2017 commented 3 years ago

Describe the bug After Power ON, the MQTT sends an ONLINE once in the field McL/config. A connected client receives this status. A new client or a new query brings an OFFLINE, although the McL is still switched on and working.

To Reproduce 1) MQTT Broker Mosquitto 2) MQTT-client Node-Red 3) MQTT-Client Laptop 4) ESP McL with SK6812

a) Node-Red is connected to the broker. The field McL/config is subscribed. Power on ESP. Node-Red MQTT says ONLINE b) Laptop establishes a new connection to the broker The McL/config field is subscribed to. I see an OFFLINE. But the ESP is ONLINE c) Node-Red MQTT-Client makes a reconnect to Broker. Subscribes to new McL/config. The answer is OFFLINE. But the ESP is ONLINE d) Power OFF from ESP all MQTT clients get an OFFLINE

Works as expected here but i think that the out message for the new status could be sent faster e.g my HASS shows the "old" state for around 5-10 seconds after switching on/off as it waits for the feedback... image

There is a programmable delay in the definitions.h file.

define DELAY_MQTT_HA_MESSAGE 5

This is so that it doesn't flood HA with too many messages all at the same time. It waits for it to be in a stable state and then sends the message. But it is configurable in the sketch.
