5 Smart Home Deals Under $100 Worth Buying This Week (Sep 17-23)
By HTB Deals Desk · Updated September 17, 2026 · 5 min read
Not every deal needs to wait for Prime Big Deal Days. This week’s best smart-home value is in small-ticket items under $100 — cameras, plugs, and accessories where the discount is real and the risk of waiting is basically zero. Five picks that owner communities actually recommend at these price points:
1. Tapo C425 2-pack — the no-subscription camera value
Wire-free 2K, battery-powered, and no monthly fee with a microSD card. The 2-pack around $99-109 is a proven buy — event pricing rarely beats it by more than a few dollars.
Typical street price: $109-$129 · Deal floor: ~$99.

2. eufy Indoor Cam S350 — dual-lens pan-tilt for less
Two lenses (wide + telephoto) with auto-tracking, no subscription needed. Owner threads rate it as the best under-$100 indoor camera this season.
Typical street price: $99-$119 · Deal floor: ~$79-89.

3. Smart plug 4-pack — the silent energy win
A 4-pack of Wi-Fi smart plugs with energy monitoring around $25-35. Not glamorous, but it is the highest-utility-per-dollar smart home purchase there is.
Typical street price: $29-$39 · Deal floor: ~$22-25.

4. Wyze Cam v4 — the budget indoor staple
2.5K indoor cam with color night vision and person detection, regularly around $30-35. The default cheap-and-good recommendation in every forum.
Typical street price: $35-$40 · Deal floor: ~$27-30.
5. Robot vacuum accessory bundles — filters and brushes
Replacement filter + brush kits for popular models run $15-25. Buying spares before the holidays beats paying event-season shipping for a $3 filter.
Typical street price: $15-$25 · Deal floor: ~$12-18.

Across Chinese owner communities
Owner consensus on cheap smart-home gear is simple: “buy the category leaders at the floor price, not the no-name alternative.” Tapo, eufy, and Wyze dominate those threads for a reason — apps that work and no subscription traps.
Honest catch
None of these will be dramatically cheaper on Oct 6-7 — that is exactly why they are safe to buy now. If a model above is at its deal floor this week, grab it; save your waiting discipline for the flagships.
Bottom line
For under $100, this week’s best moves are the Tapo C425 2-pack and a smart plug set — both at or near their price floors. Everything flagship-related stays on the wait list until Prime Big Deal Days.
