I recently came across this neat button pusher IoT gadget (used it to control the boiler in our rented accommodation): https://www.switch-bot.com/products/switchbot-bot

A less intrusive and safer alternative for those not quite comfortable with mains diy.

I installed an IoT IR blaster, since our air conditioners and ceiling lights all have IR remotes. Works fine, and if it stops working it doesn't matter since we didn't actually replace anything and lose any existing functionality.
