INKBIRD WiFi Meat Thermometer IBBQ-4T, Wireless WiFi BBQ Thermometer for Smoker, Oven | APP Calibration Temp Graph | Mobile Notification Timer Alarm | Rechargeable Digital Grill Thermometer, 4 Probes

https://a.co/d/00KL6Jfw I've been using this one for the last 5 years or so. Had to replace the probes once after they got soaked in the sink. I accidentally left it outside a couple weeks ago and it got caught in the rain so I just replaced it with the same model. I really like the app and having the versatility of 4 probes.
