Genmon working with Apple HomeKit via HomeBridge

[acesarewld]

Hi All,
I wanted to tell the group that I got my Genmon system working with Apple HomeKit via a HomeBridge plugin today. Here's what I did...

The plugin I installed is called homebridge-cmdswitch2 and I used a few Genmon API endpoints to get things working.

Examples of endpoints I used...

Exercise Generator: http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=startexercise
Start Generator: http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=start
Start + Transfer: http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=starttransfer
Stop: http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=stop

I setup the Homebridge plugin like this:
{
"platform": "cmdSwitch2",
"name": "CMD Switch",
"synchronous": true,
"switches": [
{
"name": "Exercise Generator",
"on_cmd": "curl -X GET 'http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=startexercise'",
"off_cmd": "curl -X GET 'http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=stop'"
},
{
"name": "Generator",
"on_cmd": "curl -X GET 'http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=start'",
"off_cmd": "curl -X GET 'http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=stop'"
},
{
"name": "Transfer to Generator",
"on_cmd": "curl -X GET 'http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=starttransfer'",
"off_cmd": "curl -X GET 'http://<YOUR_GENMON_SYSTEM>/cmd/setremote?setremote=stop'"
}
]
}

It works great, although it only shows the ON / OFF status based on you flipping the switch — not feedback from GenMon.
I was thinking I can write a query API that uses the engine state from the following endpoint:

http://<YOUR_GENMON_SYSTEM>/cmd/status_json

Anyway, it's up and working, I've got automations setup to turn on my Generac and transfer when my Tesla Powerwalls hit 15% so there will never be any time without power.

Let me know if you have any thoughts or questions!
