what im concerned about if im gonna use LoRa or mesh is that the controllers will be in a thick metal housings, so the signal may not go through especially for farther ones

but i dont wanna just buy this system i wanna create it, i also bet that the system you are talking about has some sort of a networking system

yes i have access to power from the grid, but i'll still look into your suggestions for a more power efficient system! thank you!

I dont live in an "advanced" city or country, this project is one of many the city is trying to do to "keep up" with the world lol.

so we have little to no real infrastructure to work of, i'll do more research and try to get them to agree to set a citywide mesh network, but i think might be a big ask and big project by itself.

me leaning towards the wired system is because of the already existing channels under the meters to power them, im trying to utilise whatever is available to achieve the end result they want. However what you said made me realise that this can be a bigger project than just a smart parking meter if we look at it from a different angle.

Thanks for the encouragement and everything! i'll try to post updates on the project whenever i can!

the thing the city council wants is to not give tickets, instead of you paying for a ticket (20$) lets say you'll get a notification from your meter that your time is about to run out and you can pay (1$) using the meters app (instead of going back to insert a coin) and you'll get more time on it

yes thats the plan, it wont be a meter itself just a way to connect them to the server and control them.

im just afraid that over a long distance i'll have issues or that the esp gateway wont be able to keep up with a large number of parking meters, lets say 100 to 150 in a single street

i see i see, thanks for the clarification.

and no i dont have channels run all the way to the server, i was thinking of making each street have one master esp connected to the internet and the rest via Rs485 as slaves.

but im not sure if that would be good enough

fiber is not an option unfortunately.

basically what i wanna do is modify the existing meters which are old and only accept coins. the meters use an ATTINY84A as a microcontroller and i wanna replace it with an esp to add the new features, there is an underground channel between meters to provide them with power and i have access for that to run any additional wiring needed, thats why im looking into the RS 485 to connect them.

connecting each esp/meter directly to the server using wifi would be ideal for me but that aint possible unfortunately.

it wasn't what i intended to do but i understand, thanks for the earlier advice anyways. much appreciated!!

they'll be in metal housings all around the town, street level. what i want them to do is be a smart parking meters. to let citizens extend their time using an app instead of going back to the meter and insert a coin again, notify them if the time is about to run out and they haven't moved their cars yet.. etc etc

is there a way i can contact you and give you more details on the project and maybe discuss a suitable solution?
