I’ve had ESPHome setup for 2 years with success using them mainly for Kogan Power Plugs to track power usage and control the switches.
During that time I’ve had 2 plugs fail (on both occasions running my 1800W kettle after 6-9 months of use). I assumed it was a power draw issue but the plug is rated to 2400W.
When the plug fails, it won’t connect to wifi, won’t manually turn on/off with the button, makes a buzzing noise, and gets warm.
Now in the last 2 weeks, I’ve had 4 plugs fail from other electrical devices (fridge, dishwasher, UPS, desk lamp). These devices were typically always on, and used merely to measure power.
Do these ESP devices have such a short lifespan? Is my config causing premature death?
My sample code for reference. Your thoughts appreciated.
