Fairness checklist
If flatmates notice your Pi only via bill or fan, fairness already failed.
- Propose overnight window or always-on cap — quiet-hours-overnight-earn-scheduling-europe-2026
- Prefer one efficient Pi over thrashing laptop stacks — multi-device-household-scoreboard-earn-apps-2026
- Offer €/month buffer if power worries flatmates
- Smart plug/UPS schedules still need agreement — shared-smartplug-ups-electricity-overnight-earn-fairness-europe-2026
- ISP fair-use binds flat IP — isp-fair-use-bandwidth-europe-2026
- Landlord AUP may ban commercial sharing — landlord-wifi-earn-apps-europe-2026
