Review: Easy To Read in Difficult Light - I purchased this humidity and temperature controller as I wanted to have a remote control device to alter heater settings when required. When I received it I immediately realised that it was an excellent visual device too, as it uses the same screen technology used on the latest Kindle Scribe, which makes it easy to read the screen in poor light and very strong light, which the cheaper displays do not use and consequently are a pain to physically read. It also operates off batteries or a USB C connection, the latter being best if you are using it tom perform frequent control functions. It was also easy to set up with the Shelly app and gave accurate readings. All in all good value for the money.
Review: Smart display - This is part of a range of devices that Shelly sell to control items around the home, as such to get the most out of it you do have to carry out some work yourself. That said, this is a very easy device to set up: insert the batteries, use a mobile phone to connect to the device, set up the wifi and away you go. The display is very clear and easy to read and the device feels good quality. It comes with a simple stand and can also be wall mounted or stuck onto a wall with the supplied pads. You can connect it to other systems and then use the readings to control other devices. Many people seem to connect it to home assistant but it can also connect to other systems with some work. I connect it to a MQTT broker and then use that to connect to Apple home where it displays the temperature and humidity. The device only connects to the Wifi system for a few seconds to update it's values and then goes back to sleep, however as the display is an e-paper display this stays on. The device updates it readings every so often (I think it states every two hours if nothings changes), or whenever they change by a certain amount, thus conserving battery life. Consequently it can be a few tenths of a degree out before it updates. It can also be triggered by a change in humidity which it also displays. I like these devices, they seem to be the best from Shelly and I intend to get several more. Note the Shelly web site states these will be upgraded to matter in the future, and when this happens you should be able to connect to a wider range of systems directly.
