Key Takeaways
- Scenario 1686 is EICR T-14 10:20 SMS — not listing, lettings, key day, rent T-3, HOA, open-house, auction, solicitor T-0 pack, gas-safety, valuation, inventory, EPC, keys-with-agent, void frost, meter-read, evening viewing, boiler, check-out, right-to-rent, AST T-28, snagging T-2, ground-rent T-7, deposit T-10, PAT T-5, completion-funds T-0, service-charge T-14, asbestos T-21, or legionella T-7.
- A T-14 that fires at HQ 14:00 after occupiers already left for work is a clock fail, not an electrics nicety.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 300 SMS lifetime, 1 device. Developer is 25,000 SMS per year.
- Starter is 2 devices; the compliance spare still counts.
- Hold board CSV until T-14 DLR drains.
- Canary the EICR SIM at 10:00, not at last night’s portal job.
Summary
Scenario 1686 is EICR access at T-14 10:20 occupier-local: notice out, T-2 chase later, board CSV held until DLR drains. Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
If the electrician is already in the cupboard and SMS is still behind “just listed,” you did not notify. You advertised the block.
Not a CodeCanyon “estate agent SMS” pack. Device meters apply — Twilio vs Android SMS gateway.

Context
PMS marks T-14 at midnight UTC. Occupiers read SMS at 10:20 local. Sales still wants a board CSV.
Free (300 SMS lifetime) is a rehearsal block. Developer is 25,000 SMS per year.
Core scenario guidance
10:20 is EICR access, not service-charge T-14 09:30. Timezone is the occupier, not HQ.
EICR-access roles
| Role | When | Typical fail |
|---|---|---|
| T-14 access 10:20 | 10:20 occupier local | Queued behind a board of new listings |
| T-2 access 10:20 | Same clock, own template | Merged into T-14 body |
| Portal OTP | Transactional, own pool | Dumped onto the EICR radio |
| Board / listings | Held until last T-14 DLR | Released at 09:50 into compliance SMS |
Cost and ownership
Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The compliance spare is a billed device. Duplicate T-14 burns airtime.
Name a 09:40–12:00 on-call for inspection mornings, not only Saturday viewings.
Operations
10:00 canary. Abort: hold board CSV, keep portal OTP, skip a second “all units” blast. Do not “resend the block.”
Security and compliance
Short bodies. No cupboard codes plus names in one SMS. Authenticate PMS hooks. Board lists are promotional.
Decision guide
Ship when 10:00 canary is green and clocks are occupier-local. Delay if phones lock in the office after 18:00. If handsets are forbidden, CPaaS for portal OTP.

- Inspection-morning on-call named.
- Device cap includes spare.
Next steps
Review device and SMS volume pricing, device setup, SMS API documentation.
Deep dive: production hardening
Cleaners unplugging USB at 09:30 is an outage at 10:20. Watch DLR, not PMS 200s.
Deep dive: scaling and failure modes
Multi-estate inspection weeks add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.
Deep dive: integration discipline
Idempotency on unit_id + offset (t14_1020|t2_1020). MCP is a REST wrapper — live fields in Developer Center.
Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
T-14 10:00 drill
Canary. Fire one T-14. Confirm DLR before board CSV. Hold listings during the wave.
