Hi,
I recent purchased 2x LB smart plugs to add to my collection. Currently, the Tasmota plugs are out of stock, so I purchased ESPHome with the intention of re-flashing them to Tasmota. I did this with the help of Adam’s helpful video. This worked but if I may suggest: It would be helpful if you provided default “known good” firmware downloads for your plugs on your site. This would save a lot of hunting and remove the risk of flashing the wrong firmware.
As instructed, I solved the problem by installing the “Lite” firmware, upgrading to the full OTA firmware and installing the LB configuration template. So far so good.
However, when I tried the plug, I found it was reading 290V odd which is very unexpected in the UK. I didn’t have time for the full calibration procedure (yet), so I backed up the settings from another working plug and restored them. This donor plug has never been calibrated by me either. Following this transplant, the new plug read 267V, which is still high. So my question…
How much calibration variability would you expect on a new plug? Is it calibrated in the factory and what range of values would you generally expect out-of-the box? Is this problem because I started with ESPHome firmware?
When I have time, I will follow the guide and do a full calibration with a known 100% resistive load. I have the gear to do this and check it. However, I was hoping for everyday use this wouldn’t be necessary. I don’t need great accuracy but 267V in the UK tells me something is very off. How accurate are the plugs? Is calibration regularly necessary?
