SwitchBot IP65 Indoor Outdoor Hygrometer Thermometer Wireless, 394ft Bluetooth Range, Refrigerator Thermometer, Dewpoint/VPD/Absolute Humidity Sensor, Free Data Storage Export, 2 Years Battery Life

Returned. Bluetooth range not working for greenhouse location.

I have tried a few Bluetooth weather devices, and this Switchbot is the cheapest and best. Physically, its advantages over similar devices are that it uses standard batteries (2xAAA, supplied) rather than a semi-randomly chosen button battery, and that it is visibly waterproof - it is a smooth white plastic box and the battery compartment lid has a seal round it. Also, the nylon hanging loop is as new after 18 months outside and is far better than a hole in the back meant to go over a hook or a nail. I was surprised, for such a cheap device, to find that it supports firmware updates, as there was a notification in the app on the first Bluetooth LE connection. It updated in a couple of minutes from 0.4 to 0.5 - an odd version number for a released product - and, as is almost always the case now, there was nothing stating what the update fixed or improved. But the facility is important. In fact, there were four firmware updates in the first three months and the current version is 0.9, although there has not been a further update for over a year. The app is also updated every few weeks, and there is the option to try out beta versions. The Bluetooth signal is evidently good, and not entirely line of sight - I can transfer data into the app from a room about 60 feet away with the device slightly hidden round a corner of the house. Caching is well implemented and only new readings are transferred unless you explicitly clear the cache from within the app; this greatly speeds up everything as the device quickly accumulates thousands of readings. When I got a new phone it took 20 minutes to transfer all the readings. Its accuracy is better than that of my old Bresser weather station, which cost several times as much but badly underestimated temperatures. Here the quoted accuracy (+ or -0.2C) is, in itself, accurate in my experience. Another Switchbot advantage, although it gets oddly low ratings in Google Play, is the app. It looks good unlike many similar apps, is simple to set up and use, and data export is easy - select a date range and readings are exported to a comma separated values file in a defined time step. Exporting a reading every minute gives a huge 1.7MB/month file, but exporting a reading every half hour amounts to 50KB/month. I can produce graphs very easily from the exported file - the big graph follows an import into Excel 2024 LTSC with no further changes and the other two graphs show what the app can display itself. The battery level remained at 100% for a long time and is 58% after 18 months so, if the app is reporting the level accurately, the (standard alkaline) batteries will probably last for longer than the two years advertised. The Switchbot is an excellent data gatherer. If it could record barometric pressure as well as temperature and humidity, it would replace everything weather-related here. I use a second (ancient) Android phone to provide a semi-permanent display. A minor issue is that the instructions state that the temperature sensor is good to -20C, but the device is recommended only to be used at 5C or greater. It has been down to -6C, with whole days below 5C, and I have noted two missed readings in over a year, which were both when the temperature was well above 0C. Most impressive was that I discovered a bug when exporting. I raised a ticket in the app; there was a comment back about three days later that it was being "escalated to senior technical staff", then after six days there was a fix available in Google Play! That speed of response is otherwise unheard of in my experience, where technical comments are often not even acknowledged. As I had two other weather stations fail during the bad weather (huge temperature and humidity fluctuations) in January 2026, I extended my "Switchbot estate" as the good build quality mentioned in the second paragraph matters ... a lot. This device was the only survivor. £15 (£11 with a coupon) is an absolute steal for something which would have cost many times that a few years ago for the same functionality and would certainly have been less robust and less easy to use.

Reseña 2: Es el tercero que tengo, y sinceramente, lo de SwitchBot empieza a ser adictivo. Este termómetro e higrómetro IP65 es fiable, resistente y muy cómodo de usar. El alcance Bluetooth de 100 metros lo hace perfecto para exteriores o zonas alejadas del router, y la batería dura hasta 2 años, lo cual es un alivio. Me encanta que puedas ver no solo la temperatura y humedad, sino también el punto de rocío, VPD y humedad absoluta. Y encima puedes exportar los datos gratuitamente para llevar un control más preciso. Reseña 1:Este termómetro e higrómetro es fácil de instalar y sincronizar; lo configuré en segundos con la app. Su tamaño compacto permite colocarlo en cualquier lugar sin estorbar, y su alcance Bluetooth de 120 metros es excelente. Mide temperatura, humedad, punto de rocío y más, complementando perfectamente al monitor de CO2 para tener un control completo del ambiente interior y exterior. Además, la exportación gratuita de datos y la batería de 2 años lo hacen aún mejor. ¡Un dúo imprescindible para un hogar inteligente!

good

Piyasada pek çok dış mekan uyumlu akıllı termometre bulunmuyor. Bu çok iyi çalışıyor. Özellikle mevsim değişim zamanlarında kullanımı. Alexa ile tamamen uyumlu! Ayrıca belirli bir sıcaklık veya nemde sizi bilgilendirir.
