How to send a notification
- 
 @sdetweil what do mean by a completion sound? Do you mean the confirmation of ‘ok’ after? If so then yes 
- 
 @alyx when u turn on or off a device, alexa does tada sound… to says it processed your request 
- 
 @sdetweil ah my one says ‘ok’ but id assume its the same 
- 
 @alyx I added your config to my MM and added debugging… and it works as expected samplemodule reports Selfie_shoot was received SampleModule received a module notification: SELFIE_SHOOT from sender: MMM-AlexaControland because u have is as onOff:false 
 u get a notification every time (on or off)I did this using the alexa app… 
- 
 @sdetweil oh… where do you think I went wrong so? 
- 
 @alyx i don’t know… i didn’t change anything in your config… if you use the alexa app to turn the plug on or off, do you see the notifications? 
- 
 @sdetweil ok I re added the selfie device on the alexa app and it found it fine but its now coming up as unresponsive 
- 
 @alyx so, discovery records the IP address of the ‘device’ and the port. so, if your pi changes ip address during boot, then it won’t work again … all my pi type devices have fixed addresses to avoid this problem… 
- 
 @sdetweil ah ok I’ll set a static! TBH I did have that concern but i was wrong to assume it was dynamic with the IP’s I’ll come back if this works or not , I have a call rn 
- 
 @alyx yeh the Alexa design is devices don’t move around, and one would only do discovery occasionally then u have to delete the devices and rediscover
