My homie-dht is behaving somewhat oddly.

With this config:
"settings":{"type":"sht30","publishInterval":60,"publishForceKey":"temperature","publishForceVal":0.0,"deepSleep":false}

I seem to get no sensor data published, although I do get some heartbeat stuff from the device:

homie/homie-dht4/$stats/signal 72
homie/homie-dht4/$stats/uptime 5819

As a further twist, if I publish a config update:

mosquitto_pub -r -t 'homie/homie-dht4/$implementation/config/set' -f ./homie-dht4

I get temps published again, but if I delete the topic:

mosquitto_pub -r -t homie/homie-dht4/$implementation/config/set -n

the updates stop. (I hope the retained config message doesn't cause constant SPIFFs rewrites of the config?)

If the sensor fails during normal system operation (tested with BME280), an endless loop occurs during BME280_Impl::readSensor(). Here, bme.takeForcedMeasurement() is called, which loops forever until a successful readout.
This kills the system, as it seems like no watchdog is triggered (maybe disabled in Homie?).
