OT stand alone problems

Hi,

my remeha calenta will not communicate with the otgw. I get only messages like that:
22:03:47.844508 R00000000 Read-Data Status: 00000000 00000000


In an other thread, i have read something like shorting X1, but i donĀ“t want to do that. I have also tried 4.2.3 firmware, but always the same problem.
The gateway is a nodo shop version with nodemcu.

When i start a selftest in installer menu of the boiler, i get some communication, but only for some seconds, then the gateway resets and show again only R00000000.

the guys from nodo shop test this gateway, but they have the same problems without thermostat. if a thermostat is connected, everything is fine.

should i buy a thermostat or have anyone an idea to fix this problem?
