Intelligent WiFi implant.

Shelly UNI is the smallest universal module that can make any old appliance smart! With this tiny, insulated chip, you can control any sensor and measure it, such as a liquid level sensor to measure the level of, or even automate the auto-filling system. No more waiting around in the morning for your coffee machine to heat its water and prepare your coffee! Just connect it to Shelly UNI and switch it on remotely as you please, or on a set schedule.  Although Shelly UNI does not include a plastic enclosure so it can be installed inside most appliances, the transparent insulation cover over the chip protects it from high humidity, dust, and the threat of short circuits.
