When I connect to module with COM connection via Putty I see only randomly generated characters
Try changing the baudrate and resetting the ESP.
Hopefully it will become logical characters.

Re: 433 MHz Transmitter & Receiver

OpenMQTTGateway or mqtt433gateway on GIT have that almost solved.
First uses RC-Switch to decode, the second uses pilight.

The second is working better for me still teething out issues though.

Re: Yewelink/Tuya WiFi Touch wall light switch

Actually, I am just wondering, ESP's were first used by people over UART with ARDUINOs in the early days before unlocking its own MCU capability. I guess these PIC based devices are following the same approach. Couldn't we just cut the trace to the pic, and wire the GPIO of the ESP directly to the r...

Re: Having difficulties with Default State

Turns out I had 2 issues:

GPIO 4 is one of the 2 default I2C lines.
Removed that, and it was okay.

Now it turns on virtually instantly after turning on.
But around 5 seconds later, it retrieves the state of the gpio that was requested over MQTT.

Now to figure out why does that happen.

Having difficulties with Default State

So, I have ESP-EASY mega running on a sonoff like clone. GPIO4 is connected to the relay. I would like it to always turn on when the board is powered on. Openhab is controlling this switch via MQTT too. I tried setting the GPIO 4 default state to Output High but it does not seem to do anything. I al...

Re: Powstro (sonoff) [multiple trials]

Hmmm, but TASMOTA saves user settings, is that not SPIFF?

Not possible to flash ESP_EASY SPIFF-less anyway?

Re: BME280 not working

It looks like the SDO might have been the culprit.
Which is weird - my other BMP280 had no issues except that I connected it on a breadboard so maybe somehow to metal contact on the breadboard helps? Or manufacturing tolerance?
Anyway, I ground SDO, and am so far having no abnormal readings so far.

If you're going to use it, don't use it with high currents.

And can you look at the used flash chip? Does it have any labels on the flash chip indicating "PUYA" ?
I couldn't find puya.
Why low current?
