## Most critical reviews (3 lowest-rated)

### 1/5 — Was never able to connect with the NEMA gateway

*2023-06-01*

I tried and followed the instructions but was never able to connect to the gateway

### 1/5 — Does not upgrade

*2022-10-02, version 1.0.5*

The app connects states “Performing Step 1 Upgrade:Success
Then when I check version has not changed.

### 2/5 — Upgraded with a glitch

*2023-03-26*

Did an upgrade and now the windmeter says wind is at 137.7 mph and says N/A on direction, also messes with temp and humidity. Before this it seemed to work well
