D1 Mini Clone never waking up from deep sleep (Tasmota v14.6.0)

[pgrutz]

I am building a simple temperature sensor using a D1 Mini and a DS18B20 sensor. I am sending the data to a MQTT broker that I have hosted on a server locally. I am going to be running this from a battery, which will be charged by solar. Everything is working except for deep sleep. Setting deepsleeptime to any value results in the chip going into deep sleep and never recovering. I have connected D0 and RST with a 10K pullup to 3.3V. Monitoring the RST / D0 pins with an oscilloscope shows that they never get a reset pulse. I can manually short to ground and the chip wakes up, transmits, and goes back to sleep as expected.

Additional Info:
DS18B20 connected: DATA -> D2 (GPIO4), VCC -> D1 (GPIO5)
ADC0 connected to input voltage via 100K resistor to monitor battery voltage
Input Voltage / ground from battery connected to 3V3 and GND respectively

Any help would be appreciated. Not sure what else to do at this point.
