getting esclamation mark in home app when clicking on switch icon
Hi all

I am using http-switch to open/close my blinds (did not find anything better to steer the as they do not send back their position so i can only either open or close them with 2 different switches)

I use stateless-reverse mode and everything works fine besides that i get esclamation marks in the home app when I click on the icons (they still work fine)... the esclamation marks remain displayed after i clicked on it but go away when i exit and enter again the home app. However, esclamation mark comes back as soon as i Click again on it...

**Does anybody know how I could get rid of the esclamation marks?**

following my json file:

	"bridge": {
		"name": "xsxsxsx",
		"username": "xsxsxsx",
		"port": xsxsx,
		"pin": "xxx-xx-xxx"
	},
	"accessories": [
		{
			"accessory": "HTTP-SWITCH",
			"name": "Switchon_EG",
			"switchType": "stateless-reverse",
			"offUrl": {
				"url": "http://xxx.xx.1.1xx/zrap/chctrl/ch1/",
				"method": "POST",
				"body": "cmd=on"
			}
		},

		{
			"accessory": "HTTP-SWITCH",
			"name": "Switchoff_EG",
			"switchType": "stateless-reverse",
			"offUrl": {
				"url": "http://xxx.xx.1.1xx/zrap/chctrl/ch1/",
				"method": "POST",
				"body": "cmd=off"
			}
		}

and a picture of my home app with the esclamation mark on the icon:
