This work was done using an ESP8266 ESP-01 device with pin2 of the device connected to a sensor output ( conditioned). The software that drives the ESP-01 was written to send the sensor output to a cloud server. The work took a little time to get everything sorted out but ultimately it worked well. Now the ESP-01 connects to the local gateway and via that gateway connects to the cloud server. A webpage with some javascript connects to the server when reading the information written there by the ESP-01.
