- Fri Oct 27, 2017 9:38 pm #71285 I'm sorry if this is a simple question and/or one that's been covered repeatedly, but I couldn't find an answer via search.

I have a Wemos D1 clone and a NodeMCU v0.9 clone from a while back. I want to connect a 433MHz receiver to it and receive codes via rcswitch. I have not had any luck with using the current version of the IDE (1.8.5) or any older versions with rcswitch. The code compiles, but I can't get any of my transmitters to show up in the serial display. I've worked with Arduino for a few projects but am not all that experienced with ESP. I've completed 1-2 very simple projects to date.

Can anyone provide a sketch and/or a combination of IDE and library versions that will work? I've spent many evenings over the last couple weeks and have made no progress.

- Sat Oct 28, 2017 8:22 am #71309 I didn't give the configuration or sketch initially as I was hoping someone could provide a known working combination of Arduino IDE, library(s), and sketch.

I have a Wemos D1 clone, NodeMCU clone, Arduino UNO R2, and a few Nani and Minis. I am aware that the UNO runs 5v while the others are all 3.3v logic.

The radio receivers I have are SRX882, 3400RF/RXB06, and RFM69. I know the RFM69 requires 3.3v logic but I beleive the other 2 are 5v. It was my understanding that the ESP was 5v tolerant despite being a 3.3v chip.

The codes I've tried are all examples I've gotten my hands on from the library, ESP8266 forum, Arduno forum, google, etc. My hardware matches the examples but no joy.

- Sat Oct 28, 2017 8:55 am #71310 I also have a number of the cheap super regenerative receiver modules. Those are all 5v AFAIK, but I've seen plenty of posts using these (as well as 3400rf and srx882) directly with ESP.
