12V Bluetooth Relay Module - Mobile Phone Wireless Remote Control Switch - IoT

After finally finding an app that would work for it (Relay Widget Bluetooth &Wifi on playstore then use command profile 2 in the app) it works good, but anytime I want to use it I have to go to Bluetooth and forget it and reconnect. I'm not happy with this item due to Bluetooth connectivity. If it gets better I'll update, but I doubt it!

It’s great.

Even with instructions provided by another person who purchased this and figured out how to make this work, no luck for me. Why should we have to deal with all this anyway ? Just provide a working app that simplifies usage like everyone else.

Works as expected. This is not a consumer grade plug and play device, it takes some technical skill to program. Here is the yaml I used in homeAssistant: esphome: name: garage-relay-esp8266 esp8266: board: esp01_1m logger: baud_rate: 0 # disable UART logging api: ota: wifi: ssid: !secret wifi_ssid password: !secret wifi_password uart: tx_pin: GPIO1 rx_pin: GPIO3 # include RX just in case baud_rate: 115200 button: - platform: template name: "Relay 1 Pulse" on_press: - uart.write: [0xA0, 0x01, 0x01, 0xA2] - delay: 200ms - uart.write: [0xA0, 0x01, 0x00, 0xA1] - platform: template name: "Relay 2 Pulse" on_press: - uart.write: [0xA0, 0x02, 0x01, 0xA3] - delay: 200ms - uart.write: [0xA0, 0x02, 0x00, 0xA2]

no app available as described for android the horrible fix is use the 'serial bluetooth terminal' app connect to the decice using the phone and the app. hold down m1-4 at the bottom and put these as the hex codes r1 on:A0 01 01 A2 off:A0 01 00 A1 r2 on:A0 02 01 A3 off:A0 02 00 A2 then look for other devices with widgets and apps 😂 but at least nobody will figure your hidden relays out.
