This is the prototype of more advanced device includes ESP2866, also has installed aboard 1wire DS18B20 temperature sensor, allows to realize independent scenarios to switch on/off of external load according to the ambient temperature. Instead of the temperature sensor other analog sensor (atmospheric pressure, water leakage, etc) can also be installed.
We have high expectations for this device, which must be claimed on the market due to the compact form factor and great opportunities for smart home automation.
