Ring doorbell pro 2 power output level 3

I installed the wired doorbell where we had an existing doorbell and made sure the transformer is the proper 16V-30V. The doorbell works but device health shows out put is 25 V and level 3 (in red), even though power is “good.” What else could be happening and what should I try? The transformer is connected directly to the fuse box in the basement and it’s not new. But since it’s the appropriate voltage, why is the app still showing output is low?

Hi @Janorin1. Can you please share a screenshot showing this messaging you’re receiving in the Ring App about your Doorbell Pro’s power level? Are you experiencing any performance concerns in addition to this message about the power level?
