Midlands Partnership University NHS Foundation Trust (MPFT) said the programme supported 105 people with multiple long-term conditions who were at high risk of needing emergency hospital treatment.
The trust used passive sensors to monitor changes in daily routines, including movement, sleep and bathroom use.
In 12 months, MPFT believes the programme saved around £728,000 in NHS bed costs.
According to the latest government figures, in 2025/26 it costs around £562 to have an NHS bed for the day in England.
News of the research comes as the government's NHS 10 Year Health Plan sets out plans to expand care into the community and increase the use of technology.
Jim, 87, who lives alone and uses the monitoring system, said the technology gave him a newfound confidence.
'My daughter can monitor my daily activities to ensure any changes can be identified,' he said. 'At the age of 87, and living alone, this gives me extra security.'
A spokesperson for MPFT's High Intensity Team, added: 'These insights have helped us deliver significant outcomes which have benefitted the team, and most importantly, our patients, including avoiding 1,300 hospital admissions over the last 12 months across 105 patients.'
