ESP32

7/24/2021 I bought this from Amazon; (?Heltec?)HiLetgo ESP32 OLED WiFi Kit ESP-32 0.96 Inch Blue OLED Display WiFi+Bluetooth CP2012 Internet Development Board for Arduino ESP8266 NodeMCU a long time ago, it's been in a box for a couple years. I thought I'd give it a whirl. from the tasmota 9.5.0 releases page I've loaded tasmota32.bin, it currently has tasmota32-display.bin. It connects, I configured GPIO25 as relay allowing me to toggle an onboard LED.

Configuration

GPIO13 Button_in

 
rule1 ON power1#state=1 do backlog power2 on; DisplayText[zs4r1c1]%var1% endon ON POWER1#state=0 do power2 off endon
rule1 1
rule3 on tele-DHT11#Temperature do var1 %value% endon
rule3 1

# cycle dht11 delay 6 seconds ds18b20 6 seconds off
rule3 on tele-DHT11#Temperature do var1 %value% endon on tele-DS18B20#Temperature do var2 %value% endon
rule1 ON power1#state=1 do backlog power2 on; DisplayText[zs3r1c1]H %var1% ; delay 60 ; DisplayText[zs3r1c1]S %var2% ; delay 60 ; power2 off endon ON POWER1#state=0 do power2 off endon
