|
|
||
| * write config struct or parameters for cmd | ||
|
|
||
| * implement a web API for simple control (fan speed, etc) | ||
|
|
||
| * add makefile | ||
| * write target for generating code for proto | ||
| * write target for build, docker image, etc | ||
|
|
||
| * [X] parse gateway operation messages using proto file | ||
|
|
||
| * [X] map and decode R-PDOs | ||
|
|
||
| * [ ] decode RMI? Does it contain useful data? | ||
|
|
||
| * [ ] write tests for pkg/comfoconnect/* | ||
|
|
||
| * [ ] design proxy/bridge that: | ||
| * [X] is a server to the app, handles registrations and sessions | ||
| * [X] forwards all other requests from the app to the gateway with the uuid of our own client (fan-in) | ||
| * [X] copies all answers from the gateway to all connected apps (fan-out) | ||
| * [ ] is half a client to the gateway, requesting updates for every known PDO | ||
| * [ ] sends keep alive messages to the gateway | ||
| * [ ] keeps metrics for all see traffic per operation type | ||
| * [ ] keep metrics for all PDOs received from the gateway | ||
