thermostat with Oled display

[elmaya]

Hi Elmaya, I have a question if you can do "4 in 1". I need 4 independent thermostatic channels in one device (nodemcuv3) (version without display and physical buttons), I want to control a 4 circuit heating distributor. I have temperature sensors in 4 rooms. I currently have 4 your thermostats installed but this is a "not very elegant" solution I noticed that the close presence of 4 esp breaks communication with them.

I will think about it.
4 relay outputs?
no push buttons (do you have your own server)?

[scoobi]

no, i'm using a public server. I don't use physical buttons, but only virtual

[elmaya]

And you've thought about what would happen if you don't have an internet connection, without push buttons you can't control.
Would that be safe?

I understand that without the Internet it will not be possible to change the temperature. but keep it offline and the thermostat will keep track of the set temperature (e.g. 20 degrees). For me, the physical buttons can be. I just won't use them. I'm worried more if esp8266 can handle all this. and whether there will be problems on the server side with handling that number of channels

Hi. can one more relay be added to the thermostat? if you can where to give it and how?

[elmaya]

Almost all Gpio are in use.
what kind of relay, for what?

[piotrekk]

I do not have an oled and do not need it, I use a thermostat to turn on the hot water heater, I set it up once and I change it very little, I have a module Nodemcu V3

I think you are in the wrong thread.
without oled:
