About this appAI proposal
Homebound Relay is a small local service that stands in for a device maker's cloud. Your robot vacuum or other connected device talks to Relay on your own network, and Relay exposes it through plain HTTPS and MQTT so Home Assistant can control it with no outside servers.
It is built for smart home enthusiasts who want local-only control but do not want to open the device, flash firmware or reverse-engineer a protocol. You pick a device profile, point your router's DNS at Relay, and pair the device. A browser dashboard shows status and traffic.
What sets it apart: guided setup that needs no hardware changes, versioned device profiles so a fix for one model reaches every owner of it, and everything staying on your network by default.

- Why this name
- Homebound says the traffic stays at home; Relay says it passes messages between the device and your tools. Two plain words.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
No-root local emulation
Relay answers the device's cloud requests on your network, so the device behaves as if the maker's servers were still there.
No member yet
MQTT and HTTPS out of the box
Each device appears as standard MQTT topics and a local HTTPS API that Home Assistant and other tools can use.
No member yet
Guided DNS and pairing
Step-by-step checks for router DNS, certificates and pairing, with a clear message when a step fails.
No member yet
Versioned device profiles
Install a profile for your model, update it when a fix is published, and roll back if it breaks.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- No loop in the product. Relay runs on the user's home network and produces nothing others see. Growth comes from content, forum posts and Home Assistant community word of mouth, not from the product's own use.
- Do they become customers?
- Each person reached is a possible buyer. Test whether Home Assistant users who find the open-source project will pay for guided setup and maintained profiles.
- First customers
- Home Assistant users who own one brand of cloud-tied robot vacuum and have tried, and given up on, rooting or manual reverse-engineering.
- Where to reach them
- Home Assistant community forum: Post a setup guide and offer early access for one vacuum brand, answering questions in public.
- Reddit smart home communities: Share a walkthrough of a vacuum running fully offline and invite testers.
- GitHub project discussions: Reach people following the open-source reverse-engineering projects and offer a guided option.
- First milestone
- Twenty owners of one vacuum brand complete setup, and at least five pay for Plus or Lifetime.

RisksAI inference
- TechnicalEach device brand uses its own protocol and certificate checks. Some devices may refuse a stand-in server, so coverage may start with very few models.
- Intellectual propertyEmulating a maker's cloud may breach terms of service or raise legal questions in some countries. Profiles need legal review.
- CommercialEnthusiasts often expect free open-source tools. Willingness to pay for the same function is unproven.
- PlatformManufacturers can change firmware or protocols, breaking profiles after an update and creating ongoing maintenance.
- DataCaptured device traffic may include account tokens or home details. It must be stored locally and handled carefully.
