ITH-20R-O - Is it possible to add an external temp sensor?

I bought the IBS-M2S wifi gateway & 3x IBS-TH20R-O as a package on Amazon. All three sensors are up and running and viewable on the Inkbird app.

A youtube video I viewed showed an external wired temperature sensor attached and working in tandem with the IBS-TH20R as a temp/humidity viewer. External & Internal temperature readings were displayed on the viewer.

Is is possible for me to connect a wired temperature sensor to my IBS-TH20R-O and get two temperature (external & internal) readings on the Inkbird app?

Hello,
If the ITH-20R-O is connected to an external temperature probe, the IBS-M2S will display the ITH-20R-O’s internal and external probe readings.
However, please note that ITH-20R-O only supports original external probes, it does not support external probes from other brands.

Hello,

Thank you for the feedback.
Please tell me the correct product code for original external probes supported by the ITH-20R-O.

Jim

Hello again,

Please respond with a list of the appropriate product number/name.
I want to source the correct original external temperature probes for the ITH-20R-O this week.

Thank you
