Wemos D1 and Thingspeak analog input problem

[jarbeni]

Hello!
Im new here and I registered just because I have an annoying problem I can´t solve..

I want analog input value to be sent to Thingspeak but it works ONLY when sleep is disabled via jumper connection.
BME280 sends temperature, humidity and pressure information correctly though.
Also RSSI value is sent to Thingspeak OK.

I have connected analog input to 3.7V battery with a 200k resistor in series.
Using the analog value calibration I have made it so show accurately the battery voltage.

Why doesn´t analog value go to Thingspeak (if sleep is enabled) when other sensors do?
