My requirement is to install a set of smart bulbs in each room in an office building. "Neither remote control or motion sensors are options". That means either I have to use voice control or voice and gesture control together.
Google Home, Amazon Echo or Apple HomeKit are the three options that came into my mind when I first think about this requirement. Yet, that is not going to be a feasible option as there are multiple rooms in the building and different people visit these rooms every day. Therefore, calling a bulb by its given label is not a feasible option.
I would like to know any existing solutions or ideas to address this.
I would like to know what sort of an IoT system would help me to address this problem? Are there any bulbs which have built-in capability to react to voice commands (This will still not solve the issue but this is for my information)?
