remotetemp uses wrong hc value

[quark654]

Hi all,

I've been trying to overwrite the thermostat room temperature value using the remotetemp command.
It's been running fine for a couple of weeks until recently, where I noticed a glitch in one of the readings. To clarify, I'll use the graph below:

Whenever a change is detected on the remote sensor 'Temperatuur', it will trigger the transmission of the remotetemp command to hc3 (ems-esp/thermostat/hc3/remotetemp).
This works fine as the yellow and blue line overlap in the graph above (as intended). However, on the 18th of December at 00:30, for some reason, hc3 receives the temperature from the hc1 thermostat.
It's a difficult problem to track down as it's happening very infrequently, so I don't have any log files available.
Do you maybe have some idea of what might be causing this issue? The easy solution might be to transmit every 5 minutes rather than on every change and as such any error will be minimal?
