Good day, can you tell me whether it is possible to connect the terminal to the flespi platform if it is not in the list of devices to connect?
It depends on the protocol that terminal uses to send data to server. If terminal uses one of the supported protocols - there are high chances that it will work with flespi. Just create a channel and check.
Otherwise - if required protocol is not supported by flespi at the moment - you may contact us in chat. We usually add new protocols for our commercial users based on SLA Advanced terms.
