The AC Infinity Cloudcom B1 is a backlit thermo-hygrometer with a 3.66 m corded probe, reading temperature, humidity and VPD on the front panel and logging all three to the AC Infinity app over Bluetooth. The corded probe is the reason to choose it over the B2: the display sits where you can see it and the sensor sits where the plants are.
Display outside, sensor inside
This is the practical argument for the B1 over the integrated-sensor B2. Hang the body on the outside of the tent and feed the probe in through a port, and you read the canopy conditions without opening anything. The same trick works for a cupboard, a subfloor hatch or a duct run: the number you want is from a place you do not want to stand in.
The head is a steel thermal-alloy probe, which matters because it responds quickly rather than lagging behind a change. You see the spike when the lights come on, not ten minutes later. Mount the body with the magnet, the wall hardware or the desk stand; the backlight makes it readable during dark period without turning a light on.
Why VPD is the number to watch
Temperature and humidity on their own are ambiguous — 26 °C at 60% RH is a different proposition in a cool room than a warm one, because what the plant experiences depends on the gap between leaf and air. VPD folds both into one figure, and the B1 calculates and displays it for you with a leaf-offset you can set. Once you are working to a VPD range, the fan and humidifier decisions get a great deal more obvious.
What the app adds
Pair over Bluetooth for historical charts, daily highs and lows, CSV export and alarm thresholds that push a notification when a limit is crossed. The display gives you now; the app gives you the last fortnight, which is what actually tells you whether your setup is stable.

FAQ
B1 or B2?
Identical unit apart from the sensor. The B1 has a 3.66 m corded probe, so the display can sit outside the space it is measuring. The B2 has the sensor built into the body, so it reads wherever the unit itself is — simpler, no cable to route, but it has to live in the space. For a grow tent the B1 is usually the better answer; for a room, a cupboard or a guitar room the B2 is tidier.
Do I need the app?
Not for the reading — temperature, humidity and VPD are on the screen. You need it for the history, the charts, the CSV export and the alarm notifications, which is most of the value. Pair it once and it logs in the background.
Can it trigger my fan?
No. The Cloudcom range reads and logs; it does not control equipment. If you want the number to drive a fan, humidifier or heater you want a UIS controller — and a B1 still earns its place next to one as a second reading point at the other end of the tent.
Is it worth buying if I already have a controller?
Often, yes. A controller reads from one probe, and one probe is one point in the room. A B1 at the opposite corner tells you whether your air movement is actually working or whether you have a warm pocket the controller never sees.
Where should the probe go?
At canopy height, in open air, out of the direct blast of a clip fan and away from the intake. A probe sitting in moving air reads the air that is passing, not the conditions the plants are in.
