Depending on your level of technical skill and willingness to risk crack things open, you can flash most Tasmota type devices with esphome and hard code it to be always on. This would go along way to eliminating software as the problem. I have done this with meters attached to my washing machine and dishwasher.
Also, the boards are also relatively simple and it is likely (although there are lots of variants) that you could remove the relay completely and bridge across the terminals. I wouldn’t plug my electric car into it (10A sustained) but you could put a led lamp through it without without much risk.
Disclaimer - I am a hobbyist, not an electrician. YMMV, keep a fire extinguisher nearby, yadda yadda







Never tried this, but it was in a selfh.st newsletter a few weeks back

I thought I would try it out when I had time. It does ‘memories’ and seems to tell a story about your data.
