I have a mysensors network setup, my config is a WemosD1 mini for a gateway, RFM69 radios for comms. Using the latest stable version of mysensors, the new RFM69 driver

The network works fine, i have 4 sensors in total. All battery powered, some are a mix of boost converters and direct power, one is 1mhz and the others are 8mhz.

My problem is that after a while the all the nodes one by one go offline, they come back when you hit the reset button and occasionally they come back to life after the contact sensor is triggered but it's a bit like a game of whack a mole keeping them all online.

Another way I have had issues is if the gateway goes offline for a few hours the nodes never recover so after sorting the gateway I have to manually reset every node.

I am using my controller and have set the system to alert me whenever a node stops communicating for 30 mins. Each node is set to transmit some data every 10 mins as a heartbeat (rx strength).

Do i need to do something on these to enable the watchdog timer? I can upload the sketches if required but for the most part they are the example BME sensor and contact switch ones.
