Last seen 7th Jul 2021 so maybe no longer active. Which I had seen this before. I started with Energenie back in around 2017, I had a problem with a social services installed extruder alarm, I wanted to be able to disable and re-enable the alarm which was up-stairs from down stairs before answering the door, and wanted it to auto switch off at the times carers were due to visit. The advantage was energenie combined both time and remote controls, and once the hub was bought then extras were not that expensive.
Second problem was central heating, and the TRV heads worked well, and were claimed to work with Nest, however they worked that well decided not to bother with Nest with that house.
So then added a light switch so could use the remote at bed side as not two way lighting in that room, all working very well, as stated by
@mri_ice lack of two way coms, resulted in not knowing it the unit had actually switched, so also got the plug in switch and energy monitor, which was very handy.
On my mothers death house was sold and new owners did not want the Energenie stuff so all removed and brought to the new house, Home Base did a sale of Energenie stuff so bought a load more, and fitted in new house, it was then we started to get problems.
1) Nest Gen 3 now fitted, but when we tried to get the TRV to work with Nest, one seems wrong way around, instead of the TRV telling Nest what to do, Nest was telling the TRV what to do, or at least some times, set Nest with app and the TRV followed, but if Nest changed due to other reason, geofencing, or timed change, it failed to change the TRV, talking to Energenie seems Nest had removed support, so had to remove the link.
2) Of the 5 light switches, now only 2 still in use, they would do their own thing, and need power at consumer unit turning off/on to get them working again, as we remove some the remaining seemed to then work OK, also had one socket turn its self into a flasher unit.
I moved to zigbee, and although zigbee smart bulbs and plug in socket switches don't report energy use, they do show on the app if switched on or off.
I do have a fair few devices
and only 4 removed, rest still working well, in the main used as simple timers, turns on lights when it is due to get dark, the 4 way extension lead turns on display lights in the living room display cabinet so if I drop off in the chair, I do not wake up in total darkness.
But the latter electronic TRV heads were eQ-3 far cheaper, bluetooth not wifi, only show target temperature but have window open feature, and seem to work better, including ability to pair them when two radiators in one room.
It seems IFTTT is now charged for, but no longer need it, only used it because only three time slots and wanted four.
I will say the energenie app is faster than the smartlife one, and will work with PC direct, where smartlife needs an emulator to work, using smart bulbs rather than smart switches allows one to also alter colour temperature and colour and dim the bulbs, however with an 8 bulb chandelier would work out expensive.
Found even with a 5 bulb chandelier the load was too low with 5 x G9 bulbs and it would flash when off, cured using load capacitor,
and shimmer when on, in the end found larger bulbs which worked
can't get G9 smart bulbs yet.
Also smart bulb on removing power defaults on, where the energenie light switch defaults off, so after a power cut lights say off, which means a danger trying to find phone or light switch in the dark.
Would be interested to see if originally posters still monitor this thread.
