常见问题 ​
位号（数据点）是什么？怎么计费？ ​
位号是设备侧的一个采集数据点（如温度、压力、开关量）。专业版按位号档位 整档计费 ：≤ 500 / ≤ 1,000 / ≤ 5,000 / ≤ 10,000 四档，超出当前档位即升入下一档，不按点位逐个计费。
注意位号数只代表接入规模，真实负载还取决于采集频率与历史数据总量：同样 500 个位号，秒级采集一天写入约 4,300 万条，小时级只有约 1.2 万条。因此每个档位同时包含历史数据 月增量 上限（500 万 – 1 亿条）与存储上限（约为月增 × 12 个月），位号数或数据量任一超出即升档；超出档位运行的部分不在支持保障覆盖范围内。社区版自托管无上述限制。
分布式（多节点）部署怎么计费？ ​
社区版的分布式能力完整开源，可自行部署运维。专业版含 1 个单机生产实例，分布式集群按节点加购（每节点 +¥99/月，年付 ¥1,188/年）；企业版节点规模不限，并含高可用架构评审。多套环境（如生产与测试）分别按实例与节点计费。
需要 36 个标准驱动之外的协议怎么办？ ​
标准驱动随所有方案免费提供。私有协议驱动按个定制开发，¥30,000/个起，交付源码与文档；企业版包含专属驱动开发额度。
月付和年付有什么区别？ ​
同一档位年付比月付整体省 20%，支持一次性开票；月付灵活，可随时升降档位，价格差在计费周期，不在功能。
如何付款和开票？ ​
邮件确认方案后，我们会提供正式报价单与服务协议，支持支付宝、微信和银行转账，企业可凭服务协议与发票入账。开票提供增值税普通发票（信息技术服务类）；增值税专用发票暂不支持，如有需要请在邮件中说明。工作日来信将在 3 个工作日内回复。
社区版可以免费商用吗？ ​
可以。IoT DC3 采用 AGPL-3.0 协议，允许商用与内部部署，只需遵守协议条款（例如向服务对象开放你的修改版源码）。当你的场景无法满足 AGPL（如闭源集成、OEM 发行），需要企业版商业授权。
专业版和社区版在功能上有区别吗？ ​
没有。档位定义的是官方承接的规模边界，不是功能解锁：平台全部能力在社区版中完整开放，位号数与数据量决定你所处的档位。
如何从社区版升级到专业版或企业版？ ​
代码同源，无需迁移或重装。保持现有部署不变，发送邮件至 pnokers@icloud.com 联系我们，即可开通相应档位与授权。
会推出云托管（SaaS）版本吗？ ​
在规划中。欢迎发送邮件至 pnokers@icloud.com 告诉我们你的规模与场景，帮助我们确定优先级。

Points & history volume
Point count is access scale — real load also depends on sampling frequency and history volume: the same 500 points write about 43M rows a day at 1-second sampling versus roughly 12k at hourly. Professional tiers cap both: points (≤ 500 / ≤ 1,000 / ≤ 5,000 / ≤ 10,000) and monthly history writes (5M – 100M rows). Exceeding either moves you up a tier.
Points or volume exceeded → next tier

FAQ ​
What is a point (tag), and how is it billed? ​
A point is one collected data point on a device (a temperature, a pressure, a switch…). Professional is billed in whole point tiers — ≤ 500 / ≤ 1,000 / ≤ 5,000 / ≤ 10,000 points. Exceeding a tier moves you to the next one; there is no per-point metering.
Point count is only access scale — real load also depends on sampling frequency and history volume: the same 500 points write about 43M rows a day at 1-second sampling versus roughly 12k at hourly. Each tier therefore also includes a monthly history-write cap (5M – 100M rows) with storage sized at roughly 12× the monthly cap; exceeding either the point count or the data volume moves you up a tier, and usage beyond your tier falls outside the support coverage. The self-hosted Community edition has no such limits.
How is distributed (multi-node) deployment billed? ​
The Community edition ships distributed capabilities fully open source — deploy and operate them yourself. Professional includes 1 standalone production instance; each cluster node is a flat add-on (+$19/node·month, $228/year). Enterprise has no node limit and includes a high-availability architecture review. Multiple environments (e.g. production and testing) are billed separately by instance and node.
What if I need a driver beyond the 36 standard ones? ​
Standard drivers are included with every plan at no cost. A private or proprietary protocol driver is a one-off custom development from $4,000 per driver, delivered with source code and docs. Enterprise includes custom driver development credits.
What is the difference between monthly and annual billing? ​
Annual saves 20% overall at the same tier and supports a single consolidated invoice. Monthly is flexible — change tiers anytime. The difference is the billing cycle, not features.
How do payment and invoicing work? ​
Once we confirm the plan by email, we provide a formal quotation and a service agreement. We accept Alipay, WeChat Pay and bank transfer; businesses can book the expense against the agreement and invoice. We issue VAT general invoices (fapiao) for IT services; special VAT invoices are not supported yet — mention it in your email if you need one. Emails are answered within 3 business days.
Can I use the Community edition commercially for free? ​
Yes. IoT DC3 is licensed under AGPL-3.0, which permits commercial and internal use as long as the license terms are followed (for example, releasing the source of your modified version to those you serve). If your scenario cannot satisfy the AGPL — such as closed-source integration or OEM distribution — you need an Enterprise commercial license.
Is Professional different from Community in features? ​
No. Tiers define the officially backed scale boundary, not a feature unlock: every capability ships fully open in the Community edition, and your point count and data volume set the tier.
How do I upgrade from Community to Professional or Enterprise? ​
The code is the same source — no migration or reinstallation needed. Keep your current deployment and reach us at pnokers@icloud.com to activate your tier and license.
Will a hosted (SaaS) edition be offered? ​
It is on the roadmap. Tell us your scale and scenario at pnokers@icloud.com to help us prioritize.
