I bought EARU RDCBC2-WIFI power meter from aliexpress Upon disassembling it (pretty difficult due to rivets holding it together) it appears that it uses a PSF-B module, so possibly based on ESP8285. The energy monitoring module appears to be cse7759b. Is there any support available for this...

>>21178402 Thank you. I figured I flash Tasmota as a generic PSF-B device, which I did and it worked. As for templates, I used Sonoff Pow R2, which seemed the closest to what device I have. And it works, values are correct, relay works. But I do have one issue. Default sample rate seems to be really low (like in minutes at least) for the values. Is there a setting within Tasmota, that would raise sample rate more? Edit: nevermind, found the command.

Upon disassembling it (pretty difficult due to rivets holding it together) it appears that it uses a PSF-B module, so possibly based on ESP8285. The energy monitoring module appears to be cse7759b.

Is there any support available for this (like tasmota or esphome) and maybe some templates/configurations?
