Missing MISO #3

Open catalinalb opened 4 years ago

Hi there, Can you provide a picture or schematic of the wiring? On my device, I have found the CLK but I miss the MISO. Probably has a different name, therefore, a picture with the actual wires soldered will solve the mist. Thank you,

Hello. haven't used these for a while, must still have one in a box somewhere so will see what I can find.

Do you know that there are newer power plug devices these days which already have a ESP8266 inside and can monitor energy usage so which can be easier to use that this approach. Hunt around for a model on Amazon/Ebay and then googling if someone has pulled that model apart and found an ESP8266 inside and how to reprogram it. Here's a start: https://www.hackster.io/news/teardown-of-a-smart-plug-or-two-6462bd2f275b

@torntrousers, I have KR-PM01-A8 power meter and the board looks very similar to yours. I don't see MISO label as well, neither on mine board nor at your picture (https://github.com/HarringayMakerSpace/WiFiPowerMeter/blob/master/docs/meter2.png?raw=true). Probably either SDI or SDO, but which one? Can you please tell us how did you wire this board with esp8266? Thanks!

I did find one of these the other day, so here it is, pulled apart again. Does that help? PXL_20220619_194249883 PXL_20220619_194238880
