Hi everyone!
I’m familiar with installing IR-readers on smartmeters (esp32). But I’m struggling with sending the signal over distance.
I live in an apartment on the third floor and my electricity meter is in the basement. I would like to transmit the signal wirelessly to my apartment. Powerline is not an option. Is there a solution via z-wave?
The control box is in my apartment. Is there any way to measure the total consumption there?
Thanks a lot!
Even for Zwave this may be too far without repeaters…
The only protocol I can think of for three floors would be LoRa.
If not mistaken you can do that via the internet. So you would connect the ESP to a WiFi network that’s available near your meter and use the esphome request plugin to push data to your instance. Do note: you need to have a subscription to many casa or similar. See HTTP Request — ESPHome
Alternative solution would be to run a hosted mqtt instance.
Maybe ESP-Now can do it, but that would require you to program the ESP yourself and you would need to make a ESP-Now gateway too.
I did read about LoRa but I think it is a bit too much effort for the result 
I’ll have a look on free wifi or perhaps I can use my neighbours’…
Not to misunderstand: MQTT would work over Internet as well, it’s not another wifi alternative, right?
ESPnow is not http request, am I correct?
ESP-Now can maybe be described as WiFi lite, but as with WiFi you need an access point for devices to communicate with.
This ESP-Now access point is just another ESP device.
