However, our deep dive also uncovered aspects that warrant careful consideration. While the remote monitoring service provides invaluable insights into operational status, battery health, and event detection, the advanced functionalities, specifically the “Cloud Connect” feature, come with a subscription cost. As one user pointed out, this feature “only works with a subscription which cost $268/year for a five pack and is not sold individually.” This pricing model presents a significant hurdle for single-unit deployments or small businesses operating on a tight budget. We believe APC could enhance the user experience by offering individual subscription tiers or including basic cloud functionality without additional cost for a single unit.
Furthermore, concerns about data privacy were raised by a user, who felt the “smart” aspect was “overrated” due to the unit’s inclination to “inform APC about everything it can regarding the unit.” While remote diagnostics are beneficial for proactive support, the extent of data collection and its implications for user privacy are legitimate points for consideration. It’s a balance between comprehensive monitoring and data sovereignty. For environments that prioritize advanced features and are willing to invest in the subscription model, SmartConnect is a powerful tool for maintaining uptime and simplifying UPS management across multiple locations. For others, the core battery backup and power conditioning remain the primary draw, with the “smart” features potentially being underutilized or viewed with caution.
