The assumption is is heat related. I can say my assumption that it's transformer related is a similar guess. I will tell you I had significantly fewer issues when I moved to a [24V 40VA Transformer](https://www.amazon.com/gp/product/B07L9X9V57/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8\u0026amp;psc=1). Better WIFI signal as well.","subreddit_name":"Ubiquiti","author":"AustinZl1"},{"body":"Yeah no problem. It’s this transformer [here](https://www.amazon.com/dp/B07L9X9V57). According to the app the other person mentioned, I’m getting sufficient power to both doorbells. They’re both showing -66 db signal so that’s a reliable WiFi signal, it could be much worse. I don’t have any problems with them other than the front doorbell likes to go offline late in the day for a little while…10 minutes max but it’s usually just a minute or two. It’s usually over 85 degrees outside when that happens and the front faces West so I’m guessing the hot sun beating on it pushes over the max ambient operating temp. The back faces east so it gets all its sun in the morning before it gets too hot and never goes offline.\r\n\r\nHope that helps!","subreddit_name":"HomeKit","author":"400HPMustang"},{"body":"Not sure if you installed your doorbells yet but now that I'm home I went up and looked at my transformer.

The multimeter and a friend might be able to figure out why the old doorbell didn't work and maybe get it going again.\r\n\r\nAssuming the OP finds the lines don't charge the battery (hopefully they do), then he/she could try to locate the small transformer and disconnect and terminate the lines running to it (turning off the power first), or maybe just disconnect the common line if proper termination would be difficult.  The transformer is most likely located in the garage or coat closet.
