The communication protocol may reduce a size of data transferred between the mobile device and control panel ensuring the user does not experience latency on their mobile device, a large bill from their wireless broadband provider, and also does not miss important update or the like from the automation system. In some embodiments, a method for a security and/or automation is described. The method may comprise generating a communication to a user, coding the communication using a pre-established user-specific code index, and transmitting the coded communication to a device associated with the user. Coding the communication may further comprise reducing a size of the communication. ## Claims ### Claim 1 A method for security and/or automation systems, comprising: generating a communication to a user; coding the communication using a pre-established user-specific code index; and transmitting the coded communication to a device associated with the user. ### Claim 2 (depends on 1) The method of claim 1, wherein coding the communication further comprises: reducing a size of the communication. ### Claim 3 (depends on 1) The method of claim 1, further comprising: generating a code index, wherein the code index is user-specific. ### Claim 4 (depends on 2) The method of claim 2, further comprising: determining when the device is connected to a wireless network; transferring the code index to the device associated with the user based at least in part on the determining. ### Claim 5 (depends on 1) The method of claim 1, further comprising: receiving an incoming coded communication from the device; and decoding the incoming coded communication using a code index. ### Claim 6 (depends on 5) The method of claim 5, further comprising: transferring the decoded communication to a module within a control panel; and executing, by the module, the decoded communication. ### Claim 7 (depends on 1) The method of claim 1, wherein the communication comprises one or more communications between the automations system and the user. ### Claim 8 An apparatus for security and/or automation systems, comprising: a processor; memory in electronic communication with the processor; and instructions stored in the memory, the instructions being executable by the processor to: generate a communication to a user; code the communication using a pre-established user-specific code index; and transmit the coded communication to a device associated with the user. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the instructions executable by the processor to code the communication further comprise: reducing a size of the communication. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the instructions are executable by the processor to: receive an incoming coded communication from the device; and decode the incoming coded communication using a code index. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the instructions are executable by the processor to: generate a code index, wherein the code index is user-specific. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the instructions are executable by the processor to: determine when the device is connected to a wireless network; transfer the code index to the device associated with the user based at least in part on the determining. ### Claim 13 (depends on 8) The apparatus of claim 8, wherein the instructions are executable by the processor to: receive an incoming coded communication from the device; and decode the incoming coded communication using a code index. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the instructions are executable by the processor to: transfer the decoded communication to a module within a control panel; and execute, by the module, the decoded communication. ### Claim 15 A method for security and/or automation systems, comprising: generating a communication to a control panel; coding the communication using a locally stored code index; and transmitting the coded communication to the control panel. ### Claim 16 (depends on 15) The method of claim 15, further comprising: connecting to a Wi-Fi connection; establishing a connection to the control panel; downloading a code index; and storing, locally, the downloaded code index. ### Claim 17 (depends on 15) The method of claim 15, further comprising: connecting to a Wi-Fi connection; establishing a connection to the control panel; updating the locally stored code index. ### Claim 18 (depends on 15) The method of claim 15, wherein coding the communication further comprises: reducing a size of the communication. ### Claim 19 (depends on 15) The method of claim 15, further comprising: receiving an incoming coded communication from the control panel; and decoding the incoming coded communication using the locally stored code index. ### Claim 20 (depends on 19) The method of claim 19, further comprising: displaying the decoded communication to a user.
