OHMIGO®ohmonwifi is a precision digitally controllable resistor that allows to digitally control and cloud connect any existing analog equipment, using a two-wire thermistor or any other RTD for temperature sensing. The connection is made via Wifi and the integrated web server. The device can generate a resistance ranging from 68.5 ohms up to 9,000,000 ohms with superior accuracy, better than 1%. During the first few seconds of operation, an LED indicates that you have connected Rout and GND with the correct polarity - If LED=RED, then switch your connection for best accuracy.
 
Supplied with software for control via Home Assistant.
 
The motherboard is the same as in Ohmigo TTL and Ohmigo USB. The difference with this product is that you can connect it to WiFi and control with other devices that are connected to the network.
