Despite some months since my last post my smarthome has continued to progress, in purchases and use cases.
I have now successfully migrated from Smartthings v1 (US) to v2 (UK) only losing one integration in the process
Voice control of my lights from Alexa (Fire TV)
A smart (Misfit) button to control my lights
Various links between my car and its new OBD2 adapter and the Nest thermostat to prepare home state and to say I'm away automatically
Have the Ring doorbell raise the lighting level of the front door lamp for 5 minutes with the IFTTT integration and the excellent "Smartrules" app
Control the gas fireplace from my control of choice in this case the Logitech Harmony remote
The last one is still a creative way of linking up the fireplace. I have a Meritek Maxitrol controller and with some trial and error I could see that connecting pins 1 & 3 of a plug socket ready for a proprietary wall switch this would trigger on & off of the fireplace. So these were connected to a Wemo maker (Made by Belkin, who incidentally have 800k Consumer devices in use globally) this in turn connects again via IFTTT to a Smartthings virtual switch and then onto the Harmony remote. The IFTTT channel for Wemo maker had the perfect scenario I needed: "On for two seconds and then off" enabling the Harmony to take control and banish another (RF remote) to the drawer and no more holding two buttons for 5 seconds either!
So IFTTT has its use and now also enables use cases where it can be automated (I would likely use Smartrules to allow really an IF this and this condition to trigger) Eg: IF motion detected in a certain area AND certain time of day AND Nest is below 20C. It could nicely complement the slow speed of underfloor heating controlled by the Nest.
Just a guy with lots of smart home tech:
