A smart plug for renters who pay late

How a $20 plug on the washer can turn a late payment into a same-day payment, what it cannot do, and the paperwork that has to come first.

September 2026 · Written for the operators listed in this directory

The problem

At $40 to $85 a month, one late renter is not worth a drive across town, and every week you wait, the set keeps working for free. Calling and texting only goes so far.

Plenty of late renters are not refusing to pay. The washer still runs whether the bill is paid or not, so it drops to the bottom of their list, under the bills that switch something off.

The idea

Put a smart plug between the washer and the wall. If a payment is past your grace period and the renter has had written notice, you switch the washer off from your phone. When they pay, you switch it back on. The machine stays in their home and nobody drives anywhere.

The goal is not to take the washer back. It is to make your bill one they pay on time, the same way they pay the power company.

Put it on the washer only. An electric dryer runs on a 240-volt, 30-amp outlet, and a plug-in smart plug will not fit it. You do not need the dryer anyway: a dryer with no washer does not do much.

Set the plug's power-on state to ON. Most plugs have this setting in their app. It means a power cut or a changed WiFi password never leaves a paying renter stuck with a dead washer.

Connect it at delivery, with the renter there. It goes on their WiFi, so they will see you do it. That is the point: nothing about this should be hidden.

Do the paperwork before the plug

This part matters more than the hardware. Put it in your rental agreement, in plain words:

Start with new renters. For someone already renting from you, sign a new agreement with this in it before a plug goes anywhere near their washer.

Why the wording matters. In 2013 the FTC settled with the rent-to-own chain Aaron's over software on rented laptops. The software could lock a laptop remotely, and franchise stores had also used it to take webcam photos and log keystrokes without telling customers. Disclose it up front, and make sure it does power and nothing else.

Rules vary by state, especially if your agreement is rent-to-own rather than a plain month-to-month rental. Have a local attorney read your clause once before you use it. This page is not legal advice.

Using it without it backfiring

What it cannot do

Where we are with it

We are setting this up for our own rentals in North Carolina, starting with the agreement language. If you want the draft clause we are working from, with blanks for your grace period and notice times, reply to the email this came in and we will send it.

If you try this, tell us what happened. What works for one operator in this directory probably works for the rest, and we will share it in the next note.
