### 1/5 — Useless with IOS

*2024-02-14*

This app is useless until Honeywell has their Bluetooth “beltclip” radio comm that connect to an IOS device.

**Developer response:** We noticed that you mentioned the belt clip radio. Please note that that belt clip radio is only needed when you use the Inspector app. MeterSense communicates with meters using a Bluetooth optical probe. If you have additional questions or concerns, please feel free to contact your Honeywell representative.
