What is Powertxt?

Powertxt is a simple remote power control switch that is fully operated and controlled by text message commands (SMS) over the mobile network (GSM). Powertxt allows users to effortlessly control mains power remotely and reboot any equipment in seconds. Powertxt is 100% cellular and has no Data/IP/WiFi capabilities making it the perfect secure solution for rebooting and remote power control. Powertxt is a more cost effective & secure solution than an IP power solution.

Powertxt is so simple and easy to use; insert a SIM card, plug it into mains power, plug in your equipment and in minutes it gives you the ability to “power cycle/reboot” your business-critical hardware simply and quickly from anywhere 24/7/365.

Powertxt also sends real time power loss text message alerts and real time temperature alerts.

How does it work?

When your equipment hangs/freezes have you ever been told by the IT department to turn the power off and then on again, well … that’s exactly what Powertxt does, it effectively performs a ‘hard reboot’ by turning the mains power to your equipment off and then on again (“rebooting it”).

Some newer routers now have the facility to perform a ‘soft reboot’ where they can reset internally but this doesn’t fix every issue, it is estimated that over 70% of all downtime events can be solved with a hard power reboot.

Every function is controlled by text message. You just send a text message from your phone to Powertxt … it’s as easy as that! You can also choose to control power automatically by time & date (e.g. Power auto on at 7am and off at 6pm every Monday – Friday) or temperature (e.g. control a heater, Power auto on when the temp drops to 5 degrees and off when it rises to 15 degrees).

Powertxt is automatically programmed to send power loss alerts as default.

Low signal? No problem! As Powertxt only uses SMS (no data) it can work in many areas where other technology fails, it works anywhere you can send a text message. Powertxt is currently used anywhere from metal cages and lockers to hospital basements with no signal issues.

Powertxt ROI

“It is estimated that over 70% of all downtime events can be solved with a hard power reboot” Most Powertxt users get a return on investment with the first call out/engineering visit saved. This then mounts to a considerable cost saving when using Powertxt for several years. Also, uptime of equipment can be just as important so by using Powertxt you can ensure equipment downtime is kept as minimal as possible.

Usage Examples

Amazon Smart Lockers – Powertxt is used on every router in the ‘Amazon Smart Lockers’ to ensure minimal downtime as customers may chose not to use this service again if they arrive at a locker that is down, these lockers need maximal uptime so customers can collect their parcel when they need to.

ATMs – Powertxt is used inside ATMs so the equipment can be rebooted if there is a comms issue, Powertxt sends real-time power loss alerts so the customer knows when it’s an issue outside of their control and it also aids security if there is a potential cyber threat as the ATM can be remotely shut down immediately. Uptime is extremely important for customer satisfaction and revenue streams.

ANPR Cameras – These can often be in dangerous locations making it extremely expensive for an engineer to visit site and in most cases the mains power supply is out of the customers control so knowing about a power outage is extremely important.

Digital Signage – Powertxt is used to reboot routers and digital signage equipment, and it is also used to save on energy costs by turning the equipment off when not required e.g. in a train station or airport, which in turn can prolong the life of the equipment.

Powertxt is used for a wide variety of equipment within many industries including digital signage, banking, smart lockers/kiosks, digital analytics, CCTV, ANPR cameras, IT & Communications, Energy & Utilities, Marine & Aquatics, Healthcare and we are finding customers using it for new applications all the time.

What SIM/network should I use? What are the approximate running costs?

UK & EU Customers – Powertxt needs a SIM card to operate, we offer UK M2M (machine to machine SIMs), EU Roaming SIMs or you can use off the shelf PAYG SIMs (pay as you go). Running costs are very low and we have negotiated special rates for SMS only SIMs, currently approx. £1.25 pm (inc 10 SMS pm). As Powertxt uses 2G SMS’s if you chose to use a PAYG SIM the unit does not work with digital only networks e.g. Three.

US Customers – Powertxt will work with both AT&T and T-Mobile. A SIM Card is effectively a small chip that goes inside Powertxt to allow it to connect to the GSM (cellular) networks. In Europe to use the GSM network ‘SIM cards’ are the only option and are readily available, however in the US it is split between CDMA and GSM (T-Mobile & AT&T). CDMA is where the network connectivity is physically built into the device and GSM uses a SIM card like Europe. Please ask your local reseller to help with M2M SIMs.


1) Any network can be used except digital-only networks such as the Three Network

2) If you choose to use a PAYG SIM please ensure you send a command to Envirotxt every few weeks/once a month (for example a temperature status request). If the SIM card is not used for several months OFCOM can sometimes force the mobile operator to take the mobile number back.

3) The device does not contain dangerous lithium batteries (Envirotxt uses ‘capacitance’ to store enough energy to send text alerts when the mains power is lost).
