If you look to this picture: https://www.elektor.nl/nodemcu-microcontroller-board-with-esp8266-and-lua?gclid=EAIaIQobChMIrpzOgMjV2gIVRZ4bCh1R7gArEAQYAyABEgI0hvD_BwE (assuming you use a nodemcu 1.0 ESP8266 board) You see Vin and GND pin. Vin is also 5V. You can solder both capacitors to this pins. Be...

Hallo riker1, I don't have a picture for solution A, but if you use a nodemcu or another board with a esp8266 installed, soldering the two capacitors on the ESP8266 board to stabilize the power of the pir shouldn't be a problem. I program my ESP8266/ESP32's from scratch, not using EASYESP or other c...

Hi, I am Eugene and for now I am automating my home now for two years using Pimatic combined on three raspberries. Sinds last december after bad experiences with arduino and NRF24L01 mysensors stuff, I started using ESP8266 Nodemcu 1.0 and Nodemcu V3 boards. I managed to create remote sensor units w...

I managed to stabilize my pir setup.

Sorry for the late respons, but it seems the same problem. I am running stable for a few months now, using pir as an alarm sensor. I upgraded my powersupply to 1 amp type. I also notices when the pir is exposed to the sun, sudden changes in sunlight triggers the pir. I am not able to solve that, you...

When using 2.1.0 or 2.2.0 compiled sketches I still got lots of false positives on my Nodemcu 1.0 board. I raised an issue on the esp8266 aruino github. There comes sugesstions to used a new SDK 1.5.3. in combination with 2.2.0, but before take that effort: I found some software that supports displa...

Update after trying board manager 2.1.0 with SDK 1.5.1 and boardmanger 2.2.0 with SDK 1.5.2. I noticed several things: Boardmanager 2.1.0 and 2.2.0 based sketched are producing false positives. Even with a Wifi power setting of 0dBm the ESP8266 is transmitting normally and still getting false positi...

Due the fact i faced watchdog reboots (approx one a day). I upgraded one of my PIR ESP8266 sensors to 2.1.0 board package. I had to remove the base64 files of this package and use another base64 library to solve my base64 problem. The SDK is also upgraded from 1.3.0 to 1.5.1 with this new package. N...

The first two commands come from the SDK as part of 2.0.0.
I guess all those commands are also present in the new 2.1.0 version of the board manager.

I have first to solve a base64 issue of 2.1.0. After fixing that I also switch to version 2.1.0 or 2.2.x. Whatever is available.

I use the Arduino IDE 1.6.8 with board manager v 2.0.0 to program the ESP8266

Using the following commands to set the requested wifi settings:

wifi_set_phy_mode(PHY_MODE_11G);
system_phy_set_max_tpw(powervalue max 82); divide by 4 for dBm value
WiFi.mode(WIFI_STA);

Right now. I am running two days stable with the Nodemcu 1.0 Pir setup. On the Nodemcu V3 I had to lower the output level to 8. Running one day stable now.

Fingers crossed.

I implemened OTA upgrades using the Arduino IDE. It runs mostly of the time fine. Sometimes i got an authentication error or an upluad error. After restarting the IDE it goes fine again.

I use it with an Nodemcu 1.0 and Nodemcu v3 Esp.

I faced exact the same issue. After deploying a HC-SR501 Pir in combination with an NodeMcu 1.0 ESP8266 module, i got tons of false positives. I tried also a V3 Nodemcu ESP8266 module, same issue. Pir directly connected to the 5v of the Nodemcu pin. I build a webserver in the ESP8266 and programmed ...
