So I’ve been reading more about Modbus, although it is really confusing because it is such a old protocol and there is so much different information and interpretation it is hard to find what you’re looking for.
But after some poking around with some other tools, I got it almost fully working, my thing file:
Bridge modbus:tcp:SE2200TCP [ host="192.168.0.214", port=1502, id=1, timeBetweenTransactionsMillis=60,
timeBetweenReconnectMillis=0, connectMaxTries=3, reconnectAfterMillis=0, connectTimeoutMillis=10000 ] {

}
Bridge poller Registers2 [ start=61440, length=10, refresh=5000, type="holding" ] {
//Setting polling to 1000 ms sometimes led to strange values in I_AC_POWER
Thing data Act_Power_Ctrl [ readStart="61441", readValueType="uint16", writeStart="61441", writeValueType="int16", writeType="holding"] // R/W to "Active Power Control Limit" on address 0xF001
}}
And the item file:
//SolarEdge modbus
Number Sensor_SE2200_ModBus_I_Status "Invertor status [MAP(SE2200_status.map):%s]" <energy> {channel="modbus:data:SE2200TCP:Registers:I_Status:number", autoupdate="false" }
Dimmer Sensor_SE2200_ModBus_Active_Power_Control_Limit "Active power control" {channel="modbus:data:SE2200TCP:Registers2:Act_Power_Ctrl:dimmer", autoupdate="false" }
The only “issue” I can’t wrap my head around right now is that the dimmer is working if I send 0 or 100, the value on the inverter will change. But, when I send 50 for example (or any other value between 1-99) it will always change to 100.
I’m not sure, but I could it has something to do with " writeValueType=“int16” " inside the data thing for address 61441, in the SolarEdge manual they say the type is uint16 (I assume for write and read then). But when I change the writeValueType to uint16, in the openHAB logging it says that this value isn’t allowed (although I see older topic’s using this value):
2024-05-20 13:07:58.631 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing 'modbus:data:SE2200TCP:Registers2:Act_Power_Ctrl' changed from ONLINE to UNINITIALIZED (HANDLER_CONFIGURATION_PENDING): {writeValueType=The value uint16 does not match allowed parameter options.

Any thoughts?
