Loaded with OpenMQTTGateway and relying on an ESP32, it brings exceptional range with its external antenna, ensuring your BLE devices stay connected through ethernet or WiFi. Source: 8 months ago

If your device is on the list of devices supported by Theengs Decoder, you can fetch its readings with OpenMQTTGateway (on ESP32) or Theengs Gateway (on a Raspberry Pi or other computer). Source: about 1 year ago

If you can find a 433Mhz version of this, you could use OpenMQTTGateway with a Lora board and use it to connect to multiple 433 style items. In fact, it may be able to handle this exact one with the 868Mhz Lora module directly. I'd check with the project forums first though. Source: over 1 year ago

Solid state relay is probably a bad idea with all the extra heat-sinking, extra cost, and chance of getting counterfeits. I do this with ESPHome & a J115F21C12VDCS.9 relay (note only the NO side is rated for 40A resistive): https://i.imgur.com/MqqOkoY.png Choose any of the temperature sensors here for air temperature sensing: https://esphome.io/ Configuration is so easy.

You can do this with a $30 Sonoff S31 running ESPHome [0]. Since the Sonoff wall switch can run a ping sensor against your server you could create a watchdog automation right on the S31 to shut off the mains power to the S31 switch and turn back on after X seconds. There are other ways you could have the S31 do operational checks but ultimately ESPHome is probably an interesting consideration and supported by tons... - Source: Hacker News / 5 months ago

They're pretty great and compatible with most things. ESPHome [1] is a great resource for getting ESP32's working nicely with HA and you can find lots of projects using it to learn from. You'll likely need to do soldering if you want to connect sensors, batteries and the like. Personally I really like what SEEED Studio [2] does with their ESP32 boards and they have nice docs. 1. https://esphome.io/. - Source: Hacker News / 5 months ago

Maybe you could set up ESPHome on the ESP32. It might make connecting those components easier, plus a decent web server built in. Then your app can be set up to access data provided by the ESPHome web server. Source: 7 months ago
