Re: Temperature sensors - which are most precise?

BME 280 shows higher temp sometimes? I'm not sure how the plugins handle the SI7021 and the BME280. Both sensors have an internal heating to dry down the humidity sensor gel pad. This should be used in some interval to keep the sensor working and precise. The heating obviously influences temperature...

Re: Sonoff Basic doesn't start when GPIO2 is LOW

The ESP8266 has some "special" GPIOs.
It can be started from a SD-Card for example, or it can be started in Flash mode.
These modes are controlled by these special GPIO's.
GPIO2 is one of these special ones. It must be "high" at boot time.
If it is "low", the ESP boots to wrong mode.

It's an analog sensor so it gives a voltage that follows the brightness.

You may use the analog input plugin.

With a bare ESP8266 it might need a voltage divider as the input should be in the range of 0....1 V.
On WeMOS and NoceMCU this voltage dividere is already there in most cases.

RX pin only receives serial, so using it - no flickering, because no sender in your circuit.

Or change your circuit:

And switch opto with log 0 instead log 1
