IBS-P02R not showing up in app with IBS M2

Installed IBS M2 and got that working with the app, but when try to add the pool thermometer it never shows up in app and not shown to select manually in app either. Have reset both units multiple times and still not syncing. IBS-PO2 is workign and screen showing temp. Have pressed transmit button multiple times.

Please refer to these steps:

Can it work?

Got it. Can the transmitter be used with more than one gateway receiver? Would like to have multiple receivers that show transmitter temperature. If so how can I purchase additional receivers that work with the IBS-Po2R transmitter

One IBS-P02R-O can connect multiple IBS-M2, there is no limit to the number.
Please search for ‘IBS-M2’ to purchase.
