TX timeout RF-link Domoticz

[301262]

Hello,

my name is Robbert en new on this forum.

I've got an issue with my RF-link on arduino (340chip), Synology NAS and Domoticz.

Here is the problem:

I can turn on or off a switch with domoticz only once and the light switches on or off. Immediately after that i get the message "error sending switch command, check hardware!".
In the log from Domoticz the following text appears: RFLink: TX time out...
After this the switch can't be used anymore.

Does someone know what to do about this?

Kind regards,

Robbert
