The GLAS Smart Thermostat is a discontinued smart thermostat manufactured by Johnson Controls. The thermostat was released in 2018 and featured a translucent OLED touchscreen, remote control through the GLAS mobile application, air-quality monitoring, energy monitoring, and integrations with digital assistants.[1]
Johnson Controls later discontinued the GLAS thermostat and ended development of the GLAS mobile application.[2] In March 2026, Johnson Controls ended support for GLAS cloud services and remote functionality.[3]
Consumer impact summary
[edit | edit source]Following the end of GLAS cloud services and remote functionality, features that depend on the GLAS mobile application or Johnson Controls' online services are no longer available, while the thermostat itself continues to perform local heating and cooling control; the company's support site stated that the thermostat "will not be impacted by the discontinuation of app support, and will continue to function as it does today."[2]
The product's original announcement had advertised remote control through the GLAS mobile application and voice control as core features.[1] Because the March 2026 shutdown disabled remote functionality on otherwise working hardware, third-party developers began documenting ways to restore local control: the open-glas project reports that the residential firmware exposes no known LAN control service and that the mobile app never communicates with the thermostat over the local network, and aims to restore local control, including temperature, humidity, air-quality and occupancy data, with eventual Home Assistant support.[4]
Incidents
[edit | edit source]End of cloud services and remote functionality (2026)
[edit | edit source]Johnson Controls ended support for GLAS thermostat cloud services and remote functionality in March 2026.[3] The company's end-of-support notices list the cloud termination for the GLAS by JCI mobile app (iOS and Android) alongside the original October 2020 discontinuation notice for the GLAS smart thermostat (model SiO2-10000) and the August 2019 removal of the Cortana feature set from the SiO2-00000 model.[3]
The loss of these services removed functionality that had originally been advertised as part of the product, including remote control through the GLAS mobile application. Johnson Controls' original product announcement described mobile-app control as one of the thermostat's available methods of operation.[1]
