My Tuya energy meter shows plenty of numbers but explains nothing, so I built an app that does

Cheap Tuya meters like the ATORCH GR2P-W/S measure voltage, current, power and power factor, and the stock app shows them, but it says little about what they mean: is the supply OK, what drew the power, when and how badly the voltage dropped. Power Trace keeps every reading on your own computer or Raspberry Pi and explains what's going on: - voltage sags and spikes: how often, how deep, how long; - when big appliances switch on and how much energy they use; - your bill at

AI 分析

痛点:廉价 Tuya 电表原厂 App 只堆砌电压/电流/功率等原始数字,不解释电压暂降、大功率电器启停和电费含义,普通用户看不懂也拿不到可行动结论

目标用户:拥有 ATORCH 等廉价 Tuya 电表、并愿意在 Windows/树莓派上自建本地监控的家庭用户与 DIY/IoT 爱好者

证据:the stock app shows them, but it says little about what they mean: is the supply OK, what drew the power... Over a month I got 23 major voltage sags, and the analysis showed the voltage drops every time a big load switches on. Next step: checking the wiring.

变现:Freemium:个人本地版免费,Pro 版按年或一次买断收费(多电表/多站点、云端同步可选、自动 PDF 报告、异常告警推送、电费优化建议、开放 API)

MVP:2 周内做:本地轮询 Tuya 设备读数(SQLite 存储)+ 电压暂降/骤升检测与聚合 + 大功率电器启停识别 + 双费率电费计算 + 0-100 健康分与原因说明,输出一页可视化仪表盘

竞品:Home Assistant Energy Dashboard、Emporia Vue、Sense、Shelly EM、Tuya Smart Life 原厂 App

摘要:作者针对 ATORCH GR2P-W/S 等廉价 Tuya 电表做了本地化分析工具 Power Trace,把原始读数转成电压暂降统计、大功率电器用电归因、自定义费率账单和 0-100 健康分,作者一个月实测到 23 次明显电压暂降并据此排查线路。数据保存在本地(设备 key 仅经 Tuya 云获取一次),支持 Windows 与树莓派/Debian。目前个人使用免费,帖子中没有任何付费意愿或收入证据,变现路径需自行验证。
