Probe is an assistant for hardware bring-up. Just talk to it: it takes you from plugging in a sensor to live data, tests, and rules that run on the device itself.
A real session: temperature, humidity and pressure streaming live from a sensor on the bench.
How it works
Each component goes through the same steps, and Probe checks every one before moving on.
Tell Probe what you're connecting. It points to the right port, draws the cable going in, and confirms the sensor's data is actually arriving, so nothing moves on until the wiring is right.

Probe applies the right settings and starts streaming. Every reading is charted live, with the current value, minimum and maximum, and a table view when you want the numbers.

Probe runs a test plan for each component, explaining each step. For an output board it clicks every relay in turn and reads it back. Afterwards you can switch any channel by hand and give it a name.

04 · Automate
Say what should happen. Probe turns it into an exact rule, sends it to the probe cube and proves it works.
"If the accelerometer tilts more than 30 degrees, turn relay 5 on."
It names the exact measurement and adds a small dead band ("off again below 28°") so the relay doesn't chatter at the threshold. You confirm with one tap.
The rule is saved to the device's flash. Probe then trips it once on purpose and checks the relay really switched. After that the rule keeps running on its own, with or without the app.
Examples
The kind of rules you can describe to Probe today. Each switches a relay, which can drive a fan, a pump, a light or a cut-off.
"If the machine tilts more than 30°, trip the motor cut-off."
Tilt > 30°→Cut-off relay
"If it gets warmer than 30 °C, turn the fan on."
Temperature > 30 °C→Fan
"If humidity goes above 70 %, switch on the dehumidifier."
Humidity > 70 %→Dehumidifier
"If the box is spun faster than 100 °/s, latch the alarm on."
Rotation > 100 °/s→Alarm, latched
"If the temperature drops below 2 °C, turn the heater on."
Temperature < 2 °C→Heater
"If the pressure falls below 1000 hPa, light the storm warning."
Pressure < 1000 hPa→Warning light
The whole picture
Projects keep everything you brought up, so you can reopen them, replay what happened and carry on later.
Early access
Probe is in early alpha. We're looking for a few teams to try it with their own hardware and tell us what's missing.
