mqttch — MQTT Control for Watch

Control your MQTT-connected smart home devices from your iPhone and Watch.

mqttch gives you a live dashboard on both your iPhone and your wrist. Configure toggles, buttons, and status indicators for any MQTT broker — then operate them from either device. The iPhone app acts as an always-on proxy so your watch stays connected without draining its battery.

Free to use with up to 3 controls. Unlock unlimited controls with a one-time purchase.
