The FlexFob is a useful addition to your YoLink system. But, I wish the YoLink folks would expand their 'handheld remote' offering - As a true fob, the FlexFob is really a bit large to be carried around with keys, which is what I envision when I see the word 'fob'. IOW, too big for a pocket.

As much as I like AAA cells, they're too large for a product in the 'fob' category. IF there really is a need for a pocketable 'fob' device, it ought to be powered from a 'coin' cell, as much as I dislike these types of batteries.

But I really wish there was a device designed to live on a table top, dresser, nightstand, etc. The existing FlexFob fails in this application because it has a rounded back, and isn't very stable when set on a surface, being designed for handheld usage. Same goes for the old YS3603 - it was really designed for handheld use - its buttons are too small for a 'tabletop' application.

Getting even fussier... I prefer hard surface buttons (like the pairing button on the YoLink plugs) over mushy rubber/silicone buttons.

So, if a 'fob' needs to esist, make it smaller and coin-cell powered. Put hardbuttons on it. Then take the old YS3603 product - keep the 2xAAA cells but give it a design intended for stationary (rather than handheld) use. Maybe drop a few buttons, but make them bigger, Add hub-based features (which it now lacks) but don't ever do away with the D2D ability present in all YoLink products. Also, consider the possibility that this re-designed YS3603 device might be able to be fited with a Decora faceplate for wall-mounted applications.

All that said, I love the YoLink products - their RF and battery performance is best in class - nothing comes close

Works great! Sends notifications to my phone when triggered. My second one.

The sensor records the temperature and humidity change in my house and it is sensitive. I can see the cycles of the temperature changes by the triggering of the heater, indicating that it senses the environmental change well.

Love the valve. Makes everything so much easier. Even my wife can use it.

I love this system because of how easy it is to set up and the remote access to it.

Easy to install and works well.

works great . I would like to see a option that would allow to base the timer on the sunset and sunrise. like to have a light turn on a 1/2 hour a after sunset etc.

Set them up, tested them, and they are cool ! Responsive too ! Pleased

Excellent product
