I posted in reply to @WBr asking how I set up Tasmota-sensors for BME280.
I have not read every post in this thread so I don't know what @9toejack's reference to a 4.7K resistor is about, but I have the ESP and sensor successfully sending data to MQTT without one.
It did trigger a memory that I read of a need for a resistor for some purpose when using a bare ESP8266, along with a picture of a development board showing the resistor for that purpose is on the board. I can't find this page now of course.
So I don't mean to undermine the advice that you need one.
I should have said "I'm not using a 4.7K resistor, what is that needed for?"
Apologies for muddying the water.
