We have had multiple requests in the forum lately from people. looking for devices that work with the new architecture and can accept input from DS18B20 probe sensors. So I’ve started this topic. If any developers have additional ones, please post.
Also: a typical DS18B20 probe will cost two or three dollars, usually sold in a pack of four or five. (That’s just for the probe sensor, not for the radio device you have to connect it to). those work fine for most HVAC or gardening applications.
However, if you are looking for one to put into an aquarium or a potable water supply, you probably need a specialty model that won’t be toxic to the fish or whatever is going to drink the water. Those usually have a different kind of plastic case and I have seen them for as much is $25 each. So just be aware of what your own use case needs are and match your requirements.
Since the probes have no radio and no internal power supply, they can handle harsh conditions (including being underwater or a wide temperature range). Then you cable them to a device which does have a radio so it can communicate to SmartThings.
The rest of this post is a list of radio devices which are known to be able to work with the 2023 SmartThings platform.

If you have any questions about a particular edge driver, please ask in the linked author thread.
- Fibaro Smart Implant. Zwave. US or EU model. Up to 4 attached probe sensors. This device requires a smartthings/Aeotec hub.
As of February 2023, this edge driver can handle an implant with up to four attached probe sensors.
Device:

- Sonoff temp/humidity sensor TH10 or TH16. Wi-Fi. Supports one attached probe. This device does not require a smartthings/Aeotech hub. It doesn’t require an edge driver. It works by first adding the device to the ewelink app and then enabling that integration through “linked services“ in the smartthings app.
Device:
- Shelley has two Wi-Fi models that can be connected to a DS18b20 probe. Because these are WiFi, they will have much better range than the Zigbee or zwave models.
@taustin has an edge driver for them.
3a) Shelly’s new UNI relay is a really interesting device, probably most similar to the old fortrezz units, but uses Wi-Fi. It’s hard to find in the US, but widely available in Europe. You can also get it shipped to the US by the manufacturer.

@taustin has an edge driver for this and many other Shelly models:

If you don’t have a smartthings/Aeotec hub, and want to use the official cloud to cloud integration, check with Shelly to make sure this model is included.
3b) Shelly 1 PM is a WiFi relay with dry contacts. One model is UL certified, which I would highly recommend for this use case. Available in several regions.
