Envirotxt Remote Power and Temperature Monitor


Do you have a relative living on their own that you're concerned about? 

Tekview's Envirotxt is a new innovative device that monitors temperature and power cuts in people’s homes. 

The device uses a SIM card to send text message alerts directly to family members/carers or to a monitoring centre.

Envirotxt is a simple and low cost way to get instant temperature alerts and instant power loss alerts. Ideal for those living with a long list of conditions, such as dementia, family members or carers can rest assured that those they care for are not too cold in winter or wasting energy by having the heating too high.

It is small, discreet and really easy to use. It doesn’t require any installation, it simply plugs into any wall socket and after sending Envirotxt a few text messages from your mobile phone it is ready to go! There is no ongoing service contract and this solution is much cheaper than paying carers to visit. 

Please note that this product does not come with a SIM card, which must be bought separately.

We recommend you take out a suitable SIM-only mobile contract with a minimum of 200 texts per month. The product requires a standard sized SIM card and we suggest you choose a provider who offers good network coverage in your area.

We’ve partnered with cable.co.uk, the leading independent website which allows you to easily compare suitable deals – you can access their service by clicking here.

Q: Why is temperature monitoring so important?

A: In total there were an estimated 31,000 excess winter deaths in England and Wales in 2012/13 and the majority of those were people aged 75 and over; this is a 29% increase on last year. Many of these excess winter deaths occur amongst older people who have underlying health issues which are exacerbated by cold weather. 

Other vulnerable groups are people with long term ill health, mental health issues, people with disabilities and babies or children under 5. 

Deaths are the most extreme instances of why temperature monitoring is so important, however, even low temperatures can make conditions such as respiratory and circulatory illnesses much worse which then has a big impact on NHS costs and resources.

It was literally a case of plug and play!

Worked first time and a pleasure to have the reassurance.
