How to get Google Home Hub or Mini to Sync your Devices

At least for me, my Smart Home is constantly changing. I may rename a switch from “vanity” to “mirror” or something, in the tp-Link app or other manufacturer’s app. For some reason, google still insists on referring to the device by the old name, and doesn’t automatically figure out the new name, the way Alexa does.

The official FAQ/Docs say to unlink the account, for example, your tp-Link account, and re-link it back to Google and it will find all the devices again. This is a pain, because when the app is relinked, Google doesn’t remember what groups/rooms you had the devices in, so you have to move them all to the correct room. Real pain in the butt for a heavily automated home like mine.

Anyway, if you just say “ok google, sync my devices” it will resync and look for new smart switches or plugs you may have added to eWelink, Sonoff, tp-Link, Shelly, etc. The old ones stay where they were, and you just have to move the new ones.

It took a lot of searching and trial and error for me to find the right thing to tell the assistant to make this happen, but that command works. Hope this helps someone.

Switch Braun BFH175US from Fahrenheit to Celsius

If you have one of these, and bought it in the US, it probably reads out in Fahrenheit. If you want it to read out in Celsius instead, ignore all the results you found on Google that didn’t work, and just do this:

Braun BFH175US

Open the battery door, and remove one or both of the batteries, look for the switch I’ve highlighted, and switch it from F to C. Reinstall the batteries, and the door, and move on with life… Your thermometer will still give you red-yellow-green warnings based on the proper scales for forehead temperature, but the readout will now be in Celsius.

Inside the battery door — Ah Ha! A switch! Lets move it.

You’re welcome. 🙂
