Found an issue with the KY002S Bi-Stable Switch; whenever ESP32 Reset button was pushed, the KY002S would toggle states. Fixed. Updated 07/29/2024 : E220-Remote-Switch project now includes KY002S Bi-Stable MOSFET Switch and the INA226 Battery Monitor with under voltage alert. E220-Remote-Switch Proj...

E220-Remote-Switch has been updated 07/19/2024 @ 19:41 EST to include E220 Sleep Mode; reducing always on current comsumption to microamp rannge!

Featuring E220, Wake-On-Radio with ESP32 Deep Sleep. E220-Remote-Switch project utilizes two, Ebye E220-900T30D RF modules and two, ESP32 microcontrollers. Current project status: INA226 and KY002S have not been implemented in this update. E220-Remote-Switch project code E220-Remote-Switch Demo Vide...

Good Morning, Working on a similar project using the Ebyte E220-900T30D; wake on radio and ESP32 deep Sleep. Project is unfinished; have issue sending message. Believe smoke is out of one of transceiver modules. Awaiting replacement. Ebyte E220 requires a RTC pin be used on the AUX pin; your device ...

Video has no sound; just a visual presentation of project.

Do you have specific question; will do my best to answer.

Very complete article on Deep Sleep and Wakeup can be found here: Renzo Mischianti's website is the most complete on the web Check out my post in the Showcase on using a transceiver to wake up the ESP32 using an external interrupt: ESP32 DEVKIT V1: nRF24L01 Switch remote, battery on/off Wish you wel...

02/20/2024 Updated project files to Github Repository. nRF24L01, transmitter and receiver have successfully turned “relay” LED on and off. Wakeup and Deep Sleep have been accomplished. Short video of nRF24L01+ Project Feedback is welcome and appreciated. “ESP32_nRF24L01_Remote_Relay” Project code Fi...

Continued to troubleshoot project code. Able to do one cyce of on and off; go into deep sleep, unable to wake. Changed CE/SS to GPIO22 and CNS to GPIO15. Made some code changes. Updated Receiver code on Github to 02/14/2024 @ 08:45 AM EST. // ESP32_nRF24L01_IRQ_Receiver.ino William Lucid 02/04/2024 ...

Monitored voltage on/off cycle on CE/SS and CSN; result moved CE/SS to GPIO15 and CSN to GPIO22. New SPI pins allow turning on and off "battery" LED. Lost Deep Sleep according to wakeup reason: ESP32_nRF24L01_IRQ_Receiver.ino Receiving... CPU0 reset reason: POWERON_RESET CPU1 reset reason: EXT_CPU_R...

Set to: rtc_gpio_pullup_en(INTERRUPT_PIN); goes from 66.05 mA awake to 10.999 mA in deep sleep. No attempt to lower current has been done.

Unable to wake from deep sleep now. -- Solved!

Updated Github project code
