Installed a Tado at my place back in December or Jan as I recall. I purchased a wired Tado thermostat to give me simple smart control over my combo boiler via Echo Dots and Apple HomeKit. It hasn’t failed me once and has been absolute rock solid. The step by step instructions on the app were accurate regarding the wiring as I was replacing a common wired Honeywell thermostat with the Tado so I just had 3 wires to deal with really. I have since purchased 2x radiator thermostats for full room control and haven’t had issues with them. The software, which is key for all three IoT devices is simple and not burdened by gimmick ads etc. The only thing it does need is the ability to ‘copy’ on/off heating schedules from one room to another. I haven’t subscribed to their monthly plan because things like geofencing, open window detection etc weren’t really a necessity for me.
That's weird, sorry couldn't be of help. It's just because I fitted this exact same thing plus 4 smart radiator thermostat myself. I had replaced existing Boss Therm BR1 connected to Worcester greenstar junior combi. Took overall 1.5 hours.
My experience with Tado - spent £500 on full kit including 8 TRVs, easy to install but wireless receiver unit failed after 72 hours. Four weeks and a 36 email exchange with arrogant Tado customer service staff they finally conceded to replace the failed unit. Email is the only means to communicate with Tado, there is no published telephone number and the online "chat" automatically responds with a promise of a minimum three hour wait for a reply. At one point Tado remotely reset all my TRVs without my consent or prior knowledge. The digital display on the TRVs is absolutely pointless, it does not reflect the room temperature. Tado failed on quality, customer serve and security and the package was returned to the retailer for full refund. I have since replaced Tado with Drayton Wiser and am totally satisfied on all counts, it was particularly easy to install and provides total control of the heating in each room via the excellant app..
The step by step guide says 'contact a qualified installer' haha Absolutely no help whatsoever.
Step by step guide should begin when you install Tado app and log in and start to register products by scanning their qr code.
