Can anyone recommend an OH-compatible Thing that can handle two thermocouples for monitoring an air conditioning system’s liquid and suction line temperatures?
Hopefully without breaking the bank?
Not really interested in trying to roll my own.
Found this one. A bit pricey. Single thermocouple.
And this one. Wi-Fi adapter is expensive though.
It doesn’t use thermocouples, but it can monitor up to 6 temperatures for a lot less money if you have Zwave.

Additionally you’ll need sensors like these:

Looks good! I can make those sensors work.
I see Amazon used to sell them. That would have made it So Easy. I wonder if it’s got something to do with tariffs?
Thanks!
You can still get it on Amazon:
But the upcharge for the non Amazon vendor is quite excessive, check the shipping!
I would consider Shelly Uni with two DS18B20 connected
I’m using the Smart Implant with two DS18B20 sensores to measure in- and out temperature of the floor-heating. Works like a charme in OH!
Do you think you could share a photo of your installed device? I’m thinking about how I might power it from thermostat voltage. Otherwise it’s a 12-volt wall wort. It appears that the Implant was designed around the Dallas part and the voltage supplied to the sensors is correct.
My device is 10 days out and I’m trying to get my ducks lined up so I can get it up and running immediately.
The documentation is pretty sketchy. All I can see from the official documentation are the connector pins on the Implant. Does the device come with the socket connector? Are there pigtail wires attached? If not is special tooling required to crimp the connectors? Are connectors available separately? So many questions.
Also, while the price on Amazon and eBay is certainly right, I think I’ve decided to order more expensive probes from another source. I don’t know if you went through the ‘counterfeit’ business, but this is a very interesting (and long) discussion:
Thanks for the recommendation. The Shelly is a lot of capability for very little money. I think I probably would have gone with it if I hadn’t already ordered an Implant. I’m already running a Z-Wave binding. I’m sure the Shelly binding is a straightforward install, but just “not right now” if you know what I mean.
Thanks again. I’m impressed enough with the Shelly that I think it deserves a link:
My implant is build in a rail-housing, so nothing to see there. I’ve connected (solder) the sensors to the wires, can’t remeber if a connector was there, don’t think so. Powered via a seperate 24V power unit since there are more modules to be powered in that area.
