Apple-aligned thermostat update puts Resideo Technologies (REZI) back in focus

Resideo Technologies (REZI) is back on investors’ radar after the business outlined a 2027 software upgrade that links its Honeywell Home ElitePRO, X7S and X8S thermostats more tightly with Apple’s new HomeView features.

The 7 day share price return of 8.5% and latest close at US$17.86 come after the stock fell about 49% over 90 days, while the 3 year total shareholder return of 79.4% still points to a very different longer term experience for investors.
