I bought a few of these three months ago.
No issues so far.
One is used for power monitoring of a fridge, the second provides state feedback to a template switch for a TV ( control is via IR ), and a third is used to send me a message when my garden tool battery is charged.
I have about 5 of them spread around my house. I like them and work well, especially the v2.
I have reflashed with update esphome, which was an interesting learning experience.
Yes I have 6 of them and they work well. Mine came with ESPHome and were easy to integrate into HA. They connect to my wifi reliably (better than my Tuya plugs do).
You can modify the colour (using heat shrink at each end) to suit if needed. The only exception to this is the use of a green/yellow earth wire which must not be used for anything else (not allowed to change it’s colour at the ends).
reading this thread i havent seen any mention of cost related to retrofitting the house with smart switches. how much did you spend approx for electrician to do the jobs recently? Is it cheaper for me to certify myself and become an electrician myself and then do the work myself ?
i recently purchased an older house built in 1970s and thinking about installing few smart switches.
Maybe I am spoiled by having two friends who are Sparkies, but turning the mains off, unscrewing the existing switch and screwing a new one on shouldn’t be expensive.
