Is there any support for retrying?

[ownaginatious]

So I have a Zen Thermostat which works fine 95% of the time with my CC26X2R1 Zigbee adapter. I have automation to set the temperature lower at night and higher during the day.

However, that sometimes fails resulting in this error:

Zigbee2MQTT:error 2020-12-23 13:37:55: Publish 'set' 'occupied_heating_setpoint' to 'zen_thermostat' failed: 'Error: Write 0x0024460000119fce/1 hvacThermostat({"occupiedHeatingSetpoint":2150}, {"timeout":10000,"disableResponse":false,"disableDefaultResponse":true,"direction":0,"srcEndpoint":null,"reservedBits":0,"manufacturerCode":null,"transactionSequenceNumber":null}) failed (Data request failed with error: 'MAC channel access failure' (225))'

It usually works when manually retrying. None of my other zigbee devices (all wall-powered) have this issue.

My theory is this sometimes fails because the thermostat isn't always listening and instead wakes up to listen periodically to conserve power (battery powered as my heating system has no C-wire).

Now I could have HomeAssistant handle retries, but it's a bit clunky.

So my question is, is there any support in zigbee2mqtt to transparently replay a message X number of times before giving up?

Thanks!
