A sonoff basic might work (will require some DIYing)
There also is other similar style smart relays (switch) that come pre-flashed making it easier like this.
Thank You, and Thanks for all the work developing it.
B"H my older kid is now past that stage and the baby is not up to it yet. If it was plug and forget, I'd do it now. But, for DIY, I'll wait till I
need it again.
