Saw that Inkbird came out with new temp controller for aquariums. It has plastic probe like newer versions of 308S controller do, but it also has WiFi capabilities now as well
- Dual Protection: The aquarium temperature controller is equipped with 2 relays to ensure that the power can be turned off under any circumstances, this will protect your fish from being hurt by overheated water.
- Two Probes: Your fish might be in danger as it is hard to know the probe is broken immediately if the temperature controller has only 1 probe. The dual probe aquarium temperature controller will alarm if the temperature difference between 2 probes is bigger than 3℃/5℉, and the app will push a notification at the same time.
- APP Notification: Pair the aquarium temperature controller with your phone via 2.4GHz Wi-Fi, the device will alarm if there are exceptions. And all exceptions will be updated to the APP, the app will push notifications to remind you.
- Continuous Heating Alarm：The heating time can be set according to your needs from 1 hour to 72 hours, the controller will alarm if water can not be heated to the setting temperature within the specified time. The temperature setting range is 20.0℃~35.0℃/68.0℉~95.0℉ and the detectable temperature range is -40℃~100℃/-40℉~212℉.

I picked up 2 from Canada site. They are smaller than 308 and plug directly into the power plug. 308 had a power chord so that was good. Not sure why they decided to go for straight plug-in for this new one, as it limits mounting options inside cabinets.
