I have a project idea and a bit of reading suggests to me that ESP32 might be the best solution. I have never touched ESP32 or anything similar. I have basic electronics understanding and capability - I built a kit Class D stereo amplifier years ago, do my only electrical work on my motorcycles etc. I'm a retired Unix admin. so am confident I can manage the software and programming aspects.
I have strange voltage issues in my home and want to record voltage over time to see if I can correlate anything that might suggest a cause. I need to be able to measure 0 to about 150VAC. Happy to go into the details of my issues if anyone is curious.
My plan is to go to AliExpress and get a 5 pack of "ESP32 Development Board WiFi+Bluetooth" and a 5 pack of "ZMPT101B AC output voltage sensor".
I'm already running Home Assistant and mqtt so am hoping I can use that as my recording and reporting engine.
My questions:
- is there anything else I'm likely to need?
- is there any way to find a good, or avoid a bad, vendor on AliExpress for those components? I don't trust the reviews.
- there are lots of "getting started" tutorials - any recommendations for a good one appropriate for background?
