in arduino software under tools menu open serial monitor and type reset and press enter, esp will reboot to factory default config.

I had a similar issue where it would read about half value every few minutes on R39 but updating to never version fixed it.
Other things to try would be a different pin on the ESP, reset command from the serial interface and flash the latest github revision again to do everything fresh.

low voltage could be an issue. do you have a pull-up resistor on the data pin?

any reason not to setup same ssid, key and encryption on all your wireless routers? I have a few running and just make sure I set the wifi channel manually to 1,6,11 to eliminate interference. WiFi devices connect to the one with the best signal on boot. I have a few phones and tablets (iCrap and An...

I had the same problem with v48 and v51
latest version 52 fixed the issue (do a reset as well configure it from scratch just in case).
and I 2nd the 10µF capacitor close to the VCC and GND on the ESP to smooth the power

@BertB this is good stuff!
thank you.
anyone know of a better way to clear the oled screen? I'm sending 16x %20 to clear the line but it makes for a slower refresh.

update to latest v52 from github, full reset and reconfigure sensors and oled, leave IP address as DHCP (reserve on router so it doesn't change) has resolved all the issues.
ESP is stable with 24h uptime, http access to the management interface, sensors and oiled work fine.

it is right next to the AP for stability testing. as it stands version 39 was stable and worked fine with DHT22 and MQTT only and after update to 51 and adding the OLED (separate power supply with common ground) the ESP is no longer stable. Web management is frequently lost after a few minutes post ...

just an update. I have installed the latest version from github and issues 1 and 2 are resolved. Web interface for settings still stops responding and esp stops responding to ping while being managed for a few minutes. rebooting the esp solves that temporary and as long as no web browser is connecte...

Hi All, I'm an old fart engineer (where did the lamps go ;-) getting back into electronics and home automation for fun. Messing around with openHAB on a Pi with some EasyESP sensors and switches. Current project now that EasyESP v49 supports oled and REST like http api is building a smart thermostat...

Hi, fairly new to the ESP8266 but had an Olimex running fine on version 39 with one DHT22 sensor attached and reporting to openHAB via MQTT. I attached an OLED and updated the software to version 49 and now experience a few issues: 1. DHT22 temperature and humidity are reported incorrectly at random...
