I use the Summons feature with the key fob twice a day to go in and out of my garage.
I try to avoid creating new threads for similar subjects, so this is somewhat related to the title of this one...
First, as far as "what could go wrong"...
Using the key fob to initiate Summon will likely drain the battery of the fob exponentially quicker compared to using it for quick actions like unlocking the car. Another member noted this in another thread recently. I used to use the app for Summon, however that was too slow of a process, so I defer to the key fob if I use Summon at all.
Second: Annoying issue with Summon and Homelink...
When using Summon to back my car out of my garage, my phone immediately receives two notifications advising that Homelink was activated. One is for the car opening the garage door and the second is for closing it.
If I wasn't already standing right there as the person who initiated Summon - watching the door open and close, these Summon/Homelink notifications may actually be helpful. Instead, they are annoying and it appears there is no way for me to disable this particular Summon notification.
I asked Freemont and they confirmed:
Thank you for your email. In response to your question on Homelink notifications, there is no setting to disable them, only to reset or delete them as you already know. If there are any further updates with the homelink notifications, we would be happy to let you know. In the mean time, we appreciate your feedback and welcome you to contact us for any further questions or concerns.
Maybe I'm just too picky? Nowadays, I rarely use Summon for the reasons mentioned above. I hope we see a drastic improvement for Summon in the next few years <-- giving myself a realistic and achievable time frame.
