Coordinationg modifications by multiple users to a shared automated environment

A non-transitory computer-readable medium including one or more sequences of instructions that, when executed by one or more processors of a first controller device in an automated environment comprising an environment model, causes:

• receiving a request to add an accessory device to the environment model, the environment model representing the automated environment;
• initiating a pair add process with the accessory device for pairing the accessory device with a second controller device in the automated environment;
• determining whether an operation succeeds, the operation comprising at least the pair add process;
• and
• in accordance with a determination that the operation succeeded:
• sending a message indicating the success to the second controller device;
• updating a first controller device local copy of the environment model to include the accessory device;
• and
• pushing the updated first controller device local copy of the environment model to the second controller device in the automated environment.

A first controller device in an automated environment comprising an environment model, the first controller device comprising:

• a memory configured to store computer-executable instructions;
• and
• one or more processors configured to access the memory and execute the computer-executable instructions to at least:
• receive a request to add an accessory device to the environment model, the environment model representing the automated environment;
• initiate a pair add process with the accessory device for pairing the accessory device with a second controller device in the automated environment;
• determine whether an operation succeeds, the operation comprising at least the pair add process;
• and
• in accordance with a determination that the operation succeeded:
• send a message indicating the success to the second controller device;
• update a first controller device local copy of the environment model to include the accessory device;
• and
• push the updated first controller device local copy of the environment model to the second controller device in the automated environment
