Wireless Doorbell with 2 Buttons 4 Receivers, PHYSEN Waterproof Door bell Chime Kit Operating at 1300-ft Range 58 Melodies 5 Volume Levels & LED Flash, Doorbell Alarm for Home/Classroom/Office Room

Totally not "smart" solution, but there are remote doorbell chimes. Wouldn't work from your phone, but if the majority of time you are calling them from the kitchen/dining area, you could just put the button in a drawer or somewhere else easy to access. Probably even easier than opening up your phone. I used this one at work previously. https://www.amazon.com/dp/B077QC3QRF?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1
