WiFi Fridge temp alarms

Hello, I’m sure there was a thread about this before but I couldn’t find it.

Can anyone recommend a fridge temp alarm that sends alerts to my phone please?

I just discovered a very low 1 degree temperature in my fridge on the digital thermometer I have.

Thankfully it was only temporary and it does happen now and then.

Freaked me out as I’ve not seen it go to 1 before. My pens were not frozen but I have lost faith!
