The device
The PocketCloudWatcher is designed for astronomers who want reliable cloud detection without the full installation of a wired system. Its key specifications:
| Dimensions | 70 × 70 × 27 mm |
|---|---|
| Weight | 85 g |
| Power | 12 V DC |
| WiFi range | 15–20 m |
| Battery life | Up to 48 hours |
The device connects via WiFi to the AAG CloudWatcher software, so it integrates directly with the same ecosystem as the full CloudWatcher — no separate software or ASCOM driver setup required.
The review
The Astronomía review focused on three aspects: build quality and form factor, cloud detection accuracy, and integration with observatory automation software.
Build quality was rated positively — the enclosure is solid, the heater keeps the IR window clear in humid conditions, and the device survived real field conditions across the test period. The IR sensor itself is the same Melexis-based unit as in the larger CloudWatcher, so detection accuracy matched expectations from the full-size device.
The WiFi range of 15–20 m was considered sufficient for most backyard observatory setups, though reviewers noted that the range would be affected by walls and building materials. For outdoor observatories the range is generally adequate without any relay.
The 48-hour battery life means the PocketCloudWatcher can run through an entire observing weekend without mains power — useful for mobile star parties or observatories where running a power cable is difficult.
Integration
Like all Lunatico CloudWatcher products, the PocketCloudWatcher is fully supported by the ASCOM driver ecosystem. It appears to planetarium and observatory control software as a standard safety monitor, meaning it can trigger automatic roof closure in N.I.N.A., Sequence Generator Pro, ACP, and other platforms without any special configuration.
The review concluded that the PocketCloudWatcher occupies a genuinely useful niche: professional-quality cloud sensing in a portable, battery-powered package at an accessible price point.
