philps hue reachable attribute, how can I fix it

Question

I made some window app that can control Bulbs. it works okay for about three months

but one of blubs makes problem. So I was trying to find out what is wrong.

here's xmlhttpRequest (I used CLIP API Debugger)

usual blubs: (XMLHttpRequest) id:14

{"state": {

"on": true,

"bri": 254,

"hue": 34704,

"sat": 198,

"effect": "none",

"xy": [

0.3228,

0.3291

],

"ct": 167,

"alert": "none",

"colormode": "xy",

"mode": "homeautomation",

"reachable": true 

}



issue: id:11

{

"state": {

"on": true,

"bri": 254,

"hue": 0,

"sat": 254,

"effect": "none",

"xy": [

0.3227,

0.329

],

"ct": 153,

"alert": "none",

"colormode": "xy",

"mode": "homeautomation",

"reachable": false

},

If anyone know this issue please let me know what's wrong with blubs...

Answer 1

reachable attribute is a read-only attribute (you can't set it), it simply tells you if the light is available or out of reach. the common causes of a light to be un-reachable is that it's set to off, it's out of range or it's dead. So

• Either turn the switch on
• If it's out of range, add another light between the bridg and that light ( as they work as a pass-through extension too )
• If it's dead replace it
• Bonus: If nothing worked try to delete it and re-add it
