WiFi power plug with temperature sensor

In the first part I’ve shown how a WiFi-power plug from Amazon can be easiely equipped with an own firmware to connect it via MQTT to the own home automation server. The manufacturer cloud is no longer needed in this case. A nice feature of the described model is a free extension pin of the integrated controller which can be used for own extensions. I want to use it to add a temperature sensor.

Arrinew / SWA1 WiFi power switch

Nightly visitors in the garden

For some month we have observed that one time a week someone opens the heavy cover of our composter, in which we deposit our organic kitchen waste. The cover is not so lightwight and it realy needs some power to open it. The visitor must be much stronger than a cat.
