I posted regarding an issue I found with Shaper which I think is related to the MQTT connection going back to EmonCMS. If that connect is interrupted I recall that MQTT will drop and not reconnect. That post involved maybe having some watchdog timer check that the connection still exists, but I’ve not seen any reply. I’m unsure if setting up maybe Mosquito might offer a workaround to force the connection back, if that’s something it could do.
