TFA30.3016.54 Wave Wireless Thermometer with Radio-Controlled Clock

How strange that the only two other reviews for this item (at the time of writing) are so old, with nothing recent. One is inaccurate too: - the time signal (from Frankfurt) is readily adapted to UK time. Just set the time zone to ‘-1’ and all will be well. (Try reading the instruction booklet!)I suggest all that reviewer’s other negativity should be ignored too. I have owned a very similar TFA Dossmann indoor-outdoor thermometer since August 2011 (the only difference being that the old one doesn’t have radio-controlled time; it has to be set manually), and it is still going.Admittedly, the outdoor transmitter failed on the old one after just less than seven years – which disappointed me, but I felt that seven years outside probably wasn’t bad – but I kept the main unit going for time and indoor temperature, and I am delighted to find that the new outdoor unit operates on the same frequency as the old one. So I now have two indoor units both picking up the signal from the one outdoor transmitter, and am enjoying the luxury of having a quick reference to outdoor temperature (as well as time and indoor temperature) in two different rooms of my house.Besides the real-time indoor and outdoor temperature (with updates several times every minute), the indoor units provide day, date and hr:min:sec time (12 or 24 hour readout options) and maximum and minimum temperatures both indoors and out are available on the push of a button. With those maximum and minimum readings comes the date and time when they were recorded.The maximum and minimum readings are not automatically reset, so whether you look at 24 hour cycles, go for the highest and lowest temperatures of the season, or just reset when you think you will is entirely up to you.Setting up is easy. The indoor receiving station and outdoor transmitter come with everything required, including a full set of batteries (4xAA), and screws and plugs for fixing the outdoor transmitter. If screwing into wood, not masonry, shorter screws might be preferred, and if the option of hanging the indoor unit on a wall is taken-up, a further screw, and possibly also a plug, will be required for that. However, the indoor unit is provided with an acceptably sturdy stand of its own, so most people will probably opt for letting it stand free on a desk, shelf or window sill.The days of the week are given their German abbreviations, not English. The abbreviations for Monday, Friday and Saturday are the same in both German and English, so that leaves Di (Dienstag), Mi (Mittwoch), Do (Donnerstag) and So (Sonntag) to learn for Tuesday, Wednesday, Thursday and Sunday. Depending on how good you are with languages, that may be an interesting diversion or a hardship, but, with the date always shown alongside, for most people the name of the day isn’t of the greatest importance.

I got this thermometer as a replacement for a previous one of the same type as it was fairly cheap. Neither thermometer was terribly accurate - I have been able to compare them both with another of a diffent manufacture and also with a local Met Office station. Overall there was a systematic error of minus one degree centigrade plus a random error difficult to quantify. You can easily see the difference when the internal and external readings are compared with the remote sensor indoors. The previous thermometer transmitter failed after a year and a half. The current one fails intermittently despite replacing batteries. Apart from these problems, the clock is linked to a German radio transmitter and so always reads one hour ahead of UK time (!) and the days are in German. But these are both minor problems as long as you are aware of them. Overall I'd give this product two and a half stars - it does give some idea of how cold or hot it is outside but I'd like something better if the price was right.Addendum: This thermometer packed up completely after a year and I have now found a much better and cheaper thermometer by Weathereye. The reliability and precision of the new thermometer really shows up how extremely poor the previous one was.

This is similar to the TFA Wireless thermometer in black. It only differs in that this one is in silver and has the radio controlled clock, which I prefer because you don't have to worry about setting the clock, particularly when the clocks change. The display is quite simple and consequently easy to read: Clock, temperature in and temperature out. Other weather stations I looked at just had too much information and would be hard to just glance at and see the temperature without looking closely. It's a neat simple little item and I believe it to be pretty accurate. TFA are a well known German brand who specialise in this type of product. The unit is inevitably made in China, but that doesn't bother me. Highly recommended.
