My apartment is often too warm once the building heating is at full temperature. I like that I can control all the radiators from the app as adjusting the individual manual radiator controls is annoying. The Nedis radiator control integrates seamlessly into Tuya / Smartlife and given that I have many other Tuya devices it beats adding yet another proprietary app for the radiators. The only thing stopping me giving 5 stars is that the time programming for these devices in the individual device controls section is not great. It seems to get confused as to the actual time. So instead I run a scene in the app to reduce the overnight temperature in the bedroom for example. I managed to get 4 from a range of sources (some amazon some not) for around 400kr each.Note: These are Zigbee, so you need a Hub. I use the Nedis combined Zigbee/bluetooth hub that plugs directly into an outlet and connects to me WiFi. Adding them to the hub is a little confusing, read the instructions carefully. You need to set them to OF and hold the button for 5 seconds (step 8 & 9)Note: This is an M30 device so you need a TA M28-M30 adaptor if you have old MMA radiators.
