Hello,
I received a brand new board from NodoShop and struggled a lot before succeeding to control my Central Heating.
I believe this is a bug. I want to share it in the hope it will be fixed.
I also found a way to get around it, it could be useful for other users!
Steps to reproduce
- Be in standalone mode (remove Thermostat from header)
- Have an empty list of Alternative Data IDs
- Try to make the boiler heat your house by using CS/CH serial commands
(Note that CS command is honored only for 1min before going back to CS=0. This is written in the doc but it took me time to understand this. So, you need to regularly send CS=x messages and send one CH=1 message.)
Expected behavior
The boiler should heat the house
Actual behavior
Boiler is never heating.
Analysis
The gateway is sending contradictory Status (ID 0) messages (master status). Sometimes it says it enables the CH bit, sometimes it says it disables the CH bit.
The boiler never even activates Central Heating because before it can do that, the gateway has already sent again a CH=0 to the boiler.

09:02:11.874188 B40120166 Read-Ack CH water pressure (MsgID=18): 1.40
It took time for me to understand what to do to make it work.
I noticed the messages sent in standalone mode are documented here:
https://otgw.tclcode.com/standalone.html#intro
They always occur in this order:
MsgID 0: Master and Slave Status flags
MsgID 25: Boiler flow water temperature
MsgID 1: Control Setpoint
UserDefined
MsgID 17: Relative Modulation Level
MsgID 27: Outside temperature
MsgID 28: Return water temperature
MsgID 14: Maximum relative modulation level setting
UserDefined
MsgID 0: Master and Slave Status flags
MsgID 25: Boiler flow water temperature
MsgID 1: Control Setpoint
MsgID 56: DHW Setpoint
MsgID 57: Max CH water Setpoint
UserDefined
MsgID 18: Water pressure in CH circuit
When comparing my messages log with this list, we quickly see that correct Status messages (CH=1) are the Status messages in the list, and wrong ones with the bug (CH=0) are those replacing the UserDefined slots.
UserDefined slots are filled by the alternative ID list. But if the list is empty, it send a Status (ID0) message.
The bug is: when filling up a UserDefined slot, if the alternative ID list is empty, the Status sent is an all-zero status, not reflecting the real status the gateway wants to send.
Work Around
The way to get around that is to add a minimum of 1 alternative ID, to make sure that UserDefined slots will never attempt to send the buggy Status message.

Re: [Bug] Flapping CH enable bit in standalone mode
Thank you for your very detailed analysis. I will work on fixing this bug.
One small remark: Only one alternative ID should be needed. The OTGW goes through the list whenever it is scheduled to send a user defined message, and starts again from the top when the list is exhausted. It doesn't map each alternative ID to a specific slot in the sequence.

Re: [Bug] Flapping CH enable bit in standalone mode
Thanks for your answer!
Yes, actually I had noticed the behavior like you say: only 1 alternative ID is enough. With 1 alternative ID, all UserDefined slots are filled with that.
I edited my post accordingly.

Re: [Bug] Flapping CH enable bit in standalone mode
Adding an alternative ID solved to "Flapping CH enable bit" problem; the "Central heating mode" stays enabled. However, the flame starts for a random short amount of time and then stops while the CH bit is still enabled and the water temperature is not yet at the desired setpoint. I'm sending the CS=xx command every 4 seconds. Is this also part of the bug or am i doing something wrong?

Re: [Bug] Flapping CH enable bit in standalone mode
Something is not working as intended. At 10:08:11.255486, the OTGW seems to have cleared the control setpoint.
Which firmware are you using? Then I can try to reproduce the situation.

Re: [Bug] Flapping CH enable bit in standalone mode
Thank you for the reply. I'm on firmware 5.5.
Re: [Bug] Flapping CH enable bit in standalone mode
I can reproduce the issue with firmware 5.5. A fix I already made for firmware 5.6 (to be released soon) also resolves this problem.
