Heartbeat not updated #4

Closed PaulvS closed 8 years ago

Hi Theo,

while browsing trough the sourcecode I see that a heartbeat is implemented. I would expect to see a mqtt message every second at stat/sonoff/heartbeat. However, I don't see this message and when issueing a cmnd/sonoff/status 1 message, the value for the heartbeat is always 0. Any clue why the heartbeat is not updating?

Partly correct. Heartbeat is send every hour, not second. My goal was to have some kind of information about auto-reboot of sonoff caused by memory leaks or unable to access the network. Every second would be to much for MQTT I think. LWT is still implemented too.

I see. I changed the code a bit on my computer to send a heartbeat every minute. In that way I can keep track of the uptime of the units. They seem to be very reliable.
