[APP][Pro] Ohmigo - Ohm On Wifi


Simplify everyday life with smart technology. OHMIGO® offers smart products that help you in the energy transition.

Ohm On WiFi - Control with resistance

OHMIGO® Ohm On WiFi can send resistance as an output signal and can replace your current temperature sensor. It is available in two versions.
In almost all types of control systems there are sensors that detect and control the current temperature.
What if one could easily replace such a temperature sensor with a new type of component that can simulate any temperature and that can be connected to the internet?

Supported flow cards


  • Temperature changed
  • Temperature becomes greater/less than Number °C
  • Resistance becomes greater/less than Number Ω


  • Set temperature to Number °C

Use cases

  • Measure temperature remotely and drive a thermostat sensor input with an Ohmonwifi to control your heating.

@TobbeG , it is alive.

But at €88 / unit, it is probably the most expensive solution out there!?

It’s worth it, larger volumes at discounted prices, of course.

I haven’t seen any solution that can generate or simulate any temperature sensor from Pt100 which is 100ohms@0’C to commonly used NTC sensors such as NTC22k which has 22kohm@25’C with 0.1’C precision.

Ohmonwifi allows you to control your old analog system from your Homey Home automation.

I think, at least with some of their products, shelly rules…
